Welcome to our collaborative guide to configuring Cisco CallManager Express, Also Known as Cisco Unified Communications Express.
I've made this Post Sticky at the top of the forum.
If you have other good reference guides Please add a comment and I'll revise this Post.
I've noticed that many questions asked here are answered inside these guides. Best part is that it is free.
Here are all the CUE admin guides

Cisco Press' Reference for CME and Unity Express
Big book. It is a bit dated as it does not cover the latest features in IOS or the UC520 but it is a great book and will teach you all of the basics you need for Cisco CME and Unity Express. A must have in your library if you are new to Cisco voice. Using the link here to Amazon.com helps support our site.
New install with 7931 phone. The literature I hae 7931 users guide has the menu, directories, and services buttons (24-21) as default. These buttons are not apearing on the phones. They work on the 796x and 794x phones. I am assuming I am missing an easy configuration, and would just like someone to let me know what those easy setps are.
thx.
Cisco IOS button commands
I've seen a bit of confusion on the site regarding Button Separators used for assigning an Ephone-dn (or extension) to an ephone.
an example of the syntax to assign a extention with ephone-dn tag 17 with a normal ring, to button one on an ephone with a tag of one would be:
ephone 1
mac-address 1111.2222.abcd
button 1:17
There are different separators available to you from the command line:
Overlay dn button commands:
An overlay set allows you to map many ephone-dns to one physical button on the phone.
an example of the syntax to assign a extention with ephone-dn tag 17, and ephone-dn18 , to button two on an ephone with a tag of 3 would be:
ephone 2
mac-address 1111.2222.abcd
button 3o17,18
There is a new application note that helps administrators secure their CME/UC500 systems and mitigate the threats of toll fraud.

Call Center Features in CallManager Express
CallManager Express supports several call center features previously unavailable in a small business environment.
In future chapters we will explore each of these in depth.
Hunt Groups
Both statically defined and dynamic hunt groups that users can log in and out of. Automatic Call Distribution (ACD)
Includes queuing by using CallManager Express' BACD service and hunt groups. Music on Hold
Either though a .wav file or external audio source AutoAttendant
Up to five autoattendants Includes dial by name and dial by number functionality Includes a script editor to create custom scripts CTI integration to several leading products including:
Microsoft Office Microsoft CRM Salesforce.com
I would like to transfer calls on my analog phones connected to my FXS ports to another phone. I've searched on Cisco.com and couldn't find anything.
My current call flow has all incoming calls going to a wireless phone connected to an FXS port that has an ephone-dn assigned to it. I need to be able to transfer calls to another phone if needed.
Thanks,
Josh
Call waiting is a feature that is enabled by default on all dual-line ephone-dns.
There are some instances where you may wish to disable Call-Waiting but keep other benifits of a dual-line ephone-dn such as consultative transfer and conferencing.
To disable a directory number from accepting call-waiting requests use the command
no call-waiting beep accept at the ephone-dn.
To make it so a specific phone cannot generate call-waiting beeps to other phones use the command
no call-waiting beep generate at the ephone-dn.
Lastly, Have you ever heard a call waiting beep on your phone, but not been able to get the other person to stop talking long enough for you to tell them you have another call?
Try call-waiting ring at the ephone-dn. This will make your phone ring rather than beep when you get a call waiting beep.
Call Manager Express Features include: We will add links to configuring these features in the future
Automatic Line Selection
Cisco CallManager Express Certification
Cisco offers an IP Communications Express Certfication.
To obtain this certification individuals must first have a CCNA and then pass the current IP Telephony Express Exam. As of this writing the current exam is 642-144 IPTX. The exam tests of Voice/VOIP concepts as well as CallManager Express and Unity Express.
The major value to this certification is for individuals looking to work with a Cisco Specialized Partner. Cisco limits the ability to sell telephony product to partners who have met their certification standards. Each Cisco partner must have a certain number of certified employees to become certified. What this means is that partners need certified people to be able to sell product. More about Cisco's partner requirements can be found here.
While Cisco's certification track to become a Cisco Certified Voice Professional (CCVP) does not include this test. Candidates for the CCIE Voice are tested in the lab environment on CallManager Express.
TonyH a Technical Marketing Engineer for CME at Cisco passed along the attached document on how to configure Call Manager Express to use SIP phones. What a great resource! Thanks Tony.
Click Here for the CME– SIP Implementation Guide version 3 in PDF format.
Although the guide shows how to configure Cisco SIP Phones you can configure 3rd party SIP phone sto work with Call Manager Express as well. You just need to remember to purchase a seat license for each phone to do it legally :)
I found a nice primer on Cisco's site to help understand how Voice Translation rules work.

What is Extension Mobility?
Very simply Extension mobility allows users to have temporary access to other physical phones connected to CME and have all of their personal settings such as lines(directory numbers), speed dials and XML services as if they were sitting at their own desk. Extension mobility is also used in desk "hoteling" environments where during the course of a day multiple people may use a phone. An example could be a 24x7 call center where 3 users each with and 8 hour shift use the same desk.
Extension Mobility on CME Concepts.
First supported on CME4.2
Every phone using extension mobility has to have a logout profile.
Phones must be enabled to use extension mobility.
A User login profile is configured to allow users to login to phones.
Can optionally support up to 50 Agents using Cisco Unified Call Center Express.
IP Phones must have a screen.
Not supported for SIP phones.
All the directory numbers must be configured before attempting these steps.
enable
configure terminal
voice logout-profile tag (You may have as many logout profiles as phones supported by the hardware)
username username password password (this is creted for this device when logg
number number type type
speed-dial speed-tag number [label label] [blf]
pin pin (optional used for call blocking)
end
Example Logout profile
CMERouter(config)# voice logout-profile 1
CMERouter(config-logout-profile)# user phone1 password 12345
CMERouter(config-logout-profile)# number 4000 type feature-ring
CMERouter(config-logout-profile)# speed-dial 1 6002
Basically, all you need to do is assign the logout profile to the ephone itself .
Using the logout-profile profile-tag where the profile tag is the tag number assigned to the logout profile you previously created
An Example Ephone Configuration
ephone 2
mac-address 0000.D111.B432
type 7970
logout-profile 1
This is all the configuration that a user will have when they login to a phone using extension mobiltity. ephone-dn and ephone templates may be used.
Configuration steps follow
enable
configure terminal
voice user-profile profile-tag
name username password password
number number type type
speed-dial speed-tag number [label label] [blf]
CMERouter(config)# voice user-profile 2
CMERouter(config-user-profile)# name user1 password 12345
CMERouter(config-user-profile)# number 5000 type feature-ring
CMERouter(config-user-profile)# speed-dial 1 6002

Wow Push to talk works on the 7921 out of the box with CME! All because (unlike Call Manager) Express has built in paging.
On CME the Push to Talk Service can be Configured in two places.
It can be configured under telephony-service to be global for all 7921 phones on a system.
or on an Ephone-template to be assigned for specific 7921s on a system.
The PTT service is activated when you depress the thumb button on a Cisco 7921 Phone.
What you do is add all of your 7921 phones to a paging group and then map the PTT Button to an intercom that triggers the paging group.
Under Telephony-service or the ephone template use the following command (case sensitive)
service phone thumbButton1 PTTH<1-6>
<1-6> is the button on the 7921 that the PTT service will use.
For a really good example of this configuration Tony Huynh from Cisco has created a video on demand. At the link below.

Creating custom ring tones for CallManager Express
or how do I get my phone the ring tone from the Fox TV show 24?
Custom Ring Tones for CallManager Express is a five step process.
Step 1 - Convert a .wav file to PCM format with a .raw extension
Step 2 - Create or modify the RingList.xml file on the CME Router
Step 3 - Upload the ringtone and RingList.xml files to the CME Router
Step 4 - Enable the TFTP process on the router to server the files.
Step 5 - Reset the phones
STEP 1 Convert a .wav file to Raw PCM
The easiest way to convert a .wav file to PCM format is using Sound Recorder, a program that usually comes installed with windows as a default. Please note the Sound Recorder that comes with Windows Vista does NOT offer this functionality.
Open the .wav file with Sound Recorder and click save as.
change the format to CCITT u-Law and 8.000khz, 8bit, then save it with a .raw extenstion.
Technically Cisco States the following:
PCM File Requirements for Custom Ring Types
The PCM files for the rings must meet the following requirements for proper playback on Cisco IP Phones:
Cisco's Requirements are documented at http://www.cisco.com/univercd/cc/td/doc/product/voice/c_callmg/3_0/admin_gd/3_0_9/a3rings.htm
STEP 2 - Create or modify the RingList.xml file on the CME Router
RingList.xml is a case sensitive file used to globally configure available ringtones on the CallManager Express router. You can copy the sample format from below into notepad and save it as RingList.xml. This file provides the list the users browse to select ringtones and the file locations the IPphone uses to find the ringtone files served up by the TFTP service on the CME router. You can have up to 50 entries in this file. The descriptions and filenames have a 25 character limit.
<CiscoIPPhoneRingList>
<Ring>
<DisplayName>MyCustomtone</DisplayName>
<FileName>mycustomtone.raw</FileName>
</Ring>
<Ring>
<DisplayName>RingTonefrom24</DisplayName>
<FileName>ctu.raw</FileName>
</Ring>
</CiscoIPPhoneRingList>
Cisco now provides a Sample RingList.xml file and Sample Ringtones at the CME section of the Software Download site. The Package does not however have the ringtone from the TV show 24. (All customers ask for this Ringtone)
STEP 3 - Upload the ringtone and RingList.xml files to the CME Router
Use the command copy tftp flash:RingList.xml and copy tftp flash:YOURringTONEname.raw
Follow our instructions on how to use TFTP or a USB flash card to upload files to the CallManager Express Router's flash.
STEP 4 - Enable the TFTP process on the router to server the files.
Enter the command tftp-server flash:RingList.xml and tftp-server flash:YOURringTONEname.raw
The tftp-server command enables the TFTP server function of the router to be able to deliver the RingList .xml and specific ringtones to the phones.
STEP 5 - Reset the phones
Reset an individual phone to test your ringtones before using the telephony-service reset all command.
To modify the default backlight behavior for Cisco IP Phones under telephone service use the service phone command in telephony-service. While some service phone commands can be placed in an ephone-template, the backlight settings can only be done under telephony-service.
Guidelines
The service phone command in telephony-service configuration mode modifies vendorConfig parameters in configuration file for phones in a Cisco Unified CME system.
The vendorConfig section of a configuration file is read by a phone's firmware when that Cisco Unified IP phone is booted. The number and type of parameters may vary from one firmware version to the next.
The Paramaters are CASE SENSITIVE!!
The IP phone that downloads the configuration file will implement only those parameters that it can support and ignore configured parameters that it cannot implement. For example, a Cisco IP phone without a backlit display cannot implement backlight parameters regardless of how they are configured.
In Cisco Unified CME 4.0 and later versions, support for creating configuration files at a phone level was added for SCCP phones. This command in ephone-template configuration mode creates an template of vendorConfig parameters that can be applied to individual SCCP phones in Cisco Unified CME. This command in ephone-template configuration mode does not work for all vendorConfig parameters.
if you use an ephone template to apply this command to one or more phones, you must also configure the cnf-file perphone command so that a separate configuration file is created for each phone, by MAC address. To apply this command in telephony-service mode to all phones of a particular type in Cisco Unified CME 4.0 and later versions, you can configure the cnf-file perphonetype command to specify that configuration files are generated by phone type.
To apply this command in telephony-service configuration mode to all phones in your Cisco Unified CME system, ensure that the system is configured for the default single per-system configuration file for all phones.
One of the default behaviors that I hate is that if the backlight is idle and a new call comes in the phone does not light up. To fix this do the below example.
Router(config)# telephony-service
Router(config-telephony)# service phone displayOnWhenIncomingCall 1
The following example shows how to set the default values for backlighting the phone display for all
Cisco Unified IP phones with backlight capabilities in Cisco Unified CME:
Router(config)# telephony-service
Router(config-telephony)# service phone daysBacklightNotActive 1,7
Router(config-telephony)# service phone backlightOnTime 07:30
Router(config-telephony)# service phone backlightOnDuration 10:00
Router(config-telephony)# service phone backlightIdleTimeout 01:00
Router(config-telephony)# create cnf-files
Router(config-telephony)# reset all
The following example shows how to set the backlighting parameters so that there is no backlighting of the phone display for all Cisco Unified IP phones with backlight capabilities until there is user interaction with the phone. The backlightIdleTimeout parameter is configured so that the backlight will switch off again after 60 seconds of inactivity.
Router(config)# telephony-service
Router(config-telephony)# service phone daysBacklightNotActive 1,2,3,4,5,6,7
Router(config-telephony)# service phone backlightOnTime 07:30
Router(config-telephony)# service phone backlightOnDuration 10:00
Router(config-telephony)# service phone backlightIdleTimeout 00.01
Router(config-telephony)# create cnf-files
Router(config-telephony)# reset all
The following example shows how to set the display parameters so that the phone display for all Cisco Unified IP phones with luminous displays are blank on Sunday (1), Monday (2), and Saturday (7):
Router(config)# telephony-service
Router(config-telephony)# service phone daysDisplayNotActive 1,2,7
Router(config-telephony)# create cnf-files
Router(config-telephony)# reset all
For security reasons you may wish to disable the PC port on an IP phone and the Settings button.
A good example of this would be a lobby phone where we don't want the visitors to be able to discover any properties of our network. As a default on CME and the UC500 depressing the settings button gives access to DHCP info and connecting a PC to the PC port on the back of a phone may give access to your data network. You may not want this behavior for some phones.
To accomplish this we need to use an ephone template an example follows:
ephone template 1
service phone pcPort 1
service phone settingsAccess 0
Note pcPort 1 turns off the phone's pc port and the zero option under settingsAccess turns of all settings access except contrast and ring tones.
The commands are case sensitive. Also be sure to assign the ephone template to an ephone! An example follows:
ephone 27
mac-address 1111.2222.3333
ephone-template 1
type 7960
button 1:27
For everyone that needs to know how to connect to CCME or UC500's together and be able to communicate via 3 or 4 digit dialing.
One thing to note. When you copy and paste be sure that the ... is translated into 3 characters. Microsoft Word turns this into a single character, which will not work in the IOS. Had to find out the hard way.
Here is the Dial Plan:

In the latest and greatest build of CME 4.3 for a ISR router there is a new feature for an ephone-dn.
It is the octo-line.
Previously you could configure a ephone-dn with a single voice port or two voice ports with the commands: ephone-dn 1
ephone-dn 2 dual-line
Now you can configure 8 voice ports on a DN with the octo-line like this:
ephone-dn 3 octo-line
This will be useful for ephone-dns associated with hardware conferencing and receptionist lines. It also is a great feature for shared lines. When using this with a shared line there are some additional features you can add into an ephone template to support the octo-line dn.
privacy - Prevent others from viewing or barging calls on an octo-line.
privacy-button - Set a shared octo line privacy button.
max-calls-per-button Defines max number of calls per octo-line button of this ephone.
As of this writing the command is not available on the UC500.
Hi All
loving all the info on this site it has been a great resource.
Just a quick question does anyone know if you can change the order of the soft buttons on the cisco 7961 phones. As because of the lack of the broadcast feature on these phones at the moment in our office we are using the group pickup feature to answer external calls, but this is hiden behind the first more button.
Can we reorder these soft buttons at all as it would make our lives so much easier.
We have 8 external lines and 18 phones and are running the system in the PBX mode hence we have to answer calls this way. Unless anyone has a better idea of how to do this i would love to know.
thanks for your help
Cheers
Cooper
Want to add true Computer Telephony Interface (CTI) features to your UC520 or Call Manager express install?
The Cisco Unified CallConnector for Windows is worth a look. It builds on the CME TSP software that is distributed with CME. This product is designed for CME and the UC00 Series. It comes in two versions Personal and Server.
The Personal Version Adds a toolbar for call control in Outlook and Internet Explorer (dial, answer, transfer, park, pickup)

It Provides a personal and corporate dialing directory and a screen pop on inbound calls with CLID/Name

Click to dial from a toolbar or highlight a number from any application

The Server version can be intalled on a Cisco MCS or customer provided server and it provides Presense information.

Presense can be extended by adding the Cisco Unified CallConnector Mobility solution. This lets users add rules to incoming calls to route them based on presense.

All in all I think this is a pretty interesting addon for CME.
Now for my product.wish list. . . It would be nice if they could figure a way to run this off of a Unity Express network module and bundle it into the core price of CME/Unity. Since Call Manager Express is targeted at Small and Medium Business, asking customers to add a server and separately licence call processing features could be a hard pill for some to swallow. Though some custmers will see the productivity enhancement and jump at it. Just my .02. I look forward to seeing this product evolve.
Does anyone know to setup a UC500 so that a call can be transferred direct to a users voicemail without the call needing to wait for the noan timeout.
This may also be a topic for Unity Express--
Is there a USER GUI to change call-forwarding settings? As administrator, I can do it using the CLI, the CCME GUI, or the Unity Express GUI. As a normal user, however, neither GUI offers that option. [I have no intention of offering CLI to users :) ] Am I missing something, or is that just the way it is?
As an aside, this particular system will also make heavy use of extension mobility, and I just learned that v4.2(1) will at least allow users to have speed dials. Up until today, I thought that was a goner too, since I was running v4.2 and could find no way to do this either.
The default behavior for an FXS port (a port that you connect an analog phone or fax to) on a cisco router is to act as a gateway port that is configured with h.323 in CallManager Express.
We can make the FXS port act just like a SCCP controlled phone like a VG224 port or phone connected to an analog telephony adapter. This way you can control the phone in CallManager express and use CME to manage hunting and other features.

is it possible to make all phones in a group ring at the same time. Ie a call comes in on fx0/0 routed to group 1 which has four phones. I want them all to ring at one, then who ever answers the call is conected
Thanks in advance
Here is a configuration example of how to get a group of phones to work and then go to auto attendant if there is no answer. The example is for FXO ports (but can be done for PRI as well). Please NOTE there are 4 phones that can answer the call...
1) First you have to get Autoattendant to work. This is done fairly easily by the configuration assistant in PBX mode. You must define an extension lets pretend I used 199 for AA.
******** VM CODE EXAMPLE FOR CCA WIZARD********
!
dial-peer voice 2001 voip
description ** cue auto attendant number **
translation-profile outgoing PSTN_CallForwarding
destination-pattern 199
b2bua
session protocol sipv2
session target ipv4:10.1.10.1
dtmf-relay sip-notify
codec g711ulaw
no vad
!
*********** END CCA EXAMPLE ***********
2) Tell your FXO ports that when a call comes in, RING a certain extension.
******* 4 FXO PORTS - ANALOG PHONE LINES*************
voice-port 0/1/0
connection plar 150 ** Unique number to match DN below
description Dial-in analog connection
caller-id enable
!
voice-port 0/1/1
connection plar 150
description Dial-in analog connection
caller-id enable
!
voice-port 0/1/2
connection plar 150
description Dial-in analog connection
caller-id enable
!
voice-port 0/1/3
connection plar 150
description Dial-in analog connection
caller-id enable
!
********* END CONFIGURATION**********
3) Create a EPHONE-DN that matches PLAR command in FXO port - You must add one DN with the same commands for every phone able to answer. In our case that is 4 DNs that are the same. Please note that when someone is on the call, the same DN can not be used by the other phones, they will not ring only a Call waiting beep will be heard by the active caller.
******** EPHONE DN EXAMPLE ************
ephone-dn 49 dual-line
number 150 *** Unique number to Match PLAR command above
name RING ALL PEOPE IN Service Department
call-forward busy 199 *** RING AutoAttendant if busy or noanswer
call-forward noan 199 timeout 10
perference 1 ** Use this DN first is available.
huntstop channel ** Dont dial 2nd line on dual line phone
no huntstop *** if the first ephone-dn is busy, call another in the group
ephone-dn 50 dual-line
number 150 *** Unique number to Match PLAR command above
name RING ALL PEOPE IN Service Department
call-forward busy 199 *** RING AutoAttendant if busy or noanswer
call-forward noan 199 timeout 10
perference 2 ** Use this DN second if available.
huntstop channel ** Dont dial 2nd line on dual line phone
no huntstop *** if the first ephone-dn is busy, call another in the group
ephone-dn 51 dual-line
number 150 *** Unique number to Match PLAR command above
name RING ALL PEOPE IN Service Department
call-forward busy 199 *** RING AutoAttendant if busy or noanswer
call-forward noan 199 timeout 10
perference 3 *** Use this DN third if available.
huntstop channel *** Dont dial 2nd line on dual line phone
no huntstop *** if the first ephone-dn is busy, call another in the group
ephone-dn 52 dual-line
number 150 *** Unique number to Match PLAR command above
name RING ALL PEOPE IN Service Department
call-forward busy 199 *** RING AutoAttendant if busy or noanswer
call-forward noan 199 timeout 10
perference 4 ** Use this DN last if available.
huntstop channel ** Dont dial 2nd line on dual line phone
********************* END EXAMPLE ******************
4) Set up each phone to RING when the company phone # is dial from a client.
Each phone already has a unique ephone-dn that defines its extension. This is created from the CCA wizard as #1 is. Each phone will have a button command. Just us an overlay or a 2nd button to answer the calls. Lets pretend that ephone-dn 10,11,12,13 were already created for the phones extensions.
************ EPHONE SETUP EXAMPLE*************
ephone 7

TonyH a TME at Cisco asked me to pass along another great document to the community. This one to help you configure Hardware Conferencing on CallManager Express and the UC520.
Software based conferencing is the default and only supports 3 parties per conference. With hardware based conferencing on CME you can support up to 8 parties per conference.
You just need the DSPs to do it!
Now after reading the attached guide you may ask me . . How many DSPs do the UC520s come with . .
Both the 8- and 16-user SKUs comes equipped with two (2) 5510 DSPs.
The 32- and 48-user SKUs both come equipped with four (4) 5510 DSP configurations.
Starting with version 4.1 of Cisco Unified CallManager Express, Cisco has introduced support for hardware based multiparty conferencing. This is a great improvement over the default software based conferencing that is also available in CallManager Express. What this means is that Call Manager Express can support up to 32 parties in a Conference call using the G.711 codec and up to 16 parties in a conference Call using the G.729a or G.729ab codecs. This is a great improvement on the 3 party limit of ad-hoc conferencing when using the software based conference feature.
To setup hardware based conferencing resources, we need to make sure we have the appropriate hardware. Cisco Call Manager Express needs DIgital Signal Processors or DSPsf or short. DSPs commonly come in the PVDM2 format that plugs into the motherboard of a Cisco 2800 or 3800 series router or a network module like the NM-HDV2 or NM-HD-2VE.
Types of conferencing available in CallManager Express
Ad-Hoc Conferencing
Ad-hoc commonly invoked by the CONFRN softkey on a phone for an impromptu conference call. Even with hardware conferencing the maximum amout of parties on a IP phone is 8.
Meet Me Conferencing
Previously only available in full blown CallManager. An admin can define a conference directory number that can be given out or a meet-me softkey can be used for users to join into a conference. The conference creator uses the meet me softkey to invoke the conference and has control over the participants. A meet me conference can have up to 32 parties (G.711).

Cisco has prepared a great guide to setting up all of these features at http://www.cisco.com/univercd/cc/td/doc/product/voice/its/cme41/htmpconf.pdf
Has anyone setup the Nokia cell phones with SCCP to work with CME? I'm trying to figure out how to have single number reach for these users. How can we have CME redirect the calls automatically to the cell number when they leave the office and the SCCP client becomes unregistered.
The closest thing I can do now is use "call-forward noan..." to the cell number. This would cause it to ring as a sccp phone and then in cell mode in the office if not answered in the office and use the cell voicemail which is lame.
Also, anyone know how to have a single voicemail on CUE rather than a CUE mailbox and a cellular mailbox the user needs to check?
Thanks
How to Create broadcast hunt groups in CallManager Express
CallManager Express supports three types of hunt groups out of the box.
Some users desire a hunt group that rings on all phones at once. In the full blown CallManager world this is referred to as a "broadcast hunt group".
To make CallManager Express emulate this broadcast hunting we can use Overlay DNs.
Lets say our help desk has extension 4357( 4357 spells help on a phone touchpad)
Plar to extension 4357 from your fxo ports.
Overlay extension 4357 on to multiple phones

That should work.
