Welcome to the community for Cisco CallManager Express and the Cisco Unified Communications 500 products such as the UC520. Our goal is to provide configuration examples and explanations to help you get the most out of your Cisco VOIP system.
The content on this site is above and beyond what is covered in the Cisco Authorized Training materials. For a good hands on learning experience we recommend Sitting the one week IPTX class at a Cisco Authorized Learning Partner like Global Knowledge.

Saurabh V a TME at Cisco gave me the following information regarding the new IP phone models.<

Cisco has released two New IP Phone Expansion modules the 7915 and 7916.

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).
I found a great white paper on Cisco's site for configuring the 7921 with the integrated wi-fi in the UC520.
It is Titled :
7921 Phones in SBCS Environment Configuration Guide
Thought I would give back a little to a community that has helped so much with a lot of CME and UC500 questions I've had. Here's an issue I ran into with the new 3911 and CME.
From my reliable sources, a new ip phone is already in beta test internally at cisco. What it has new, integrated 24 (or more) buttons with dedicated display.
The CCA 1.6 release is a minor release that has the following feature enhancements:
1) Support for the Unified Communications 500 series phones
2) Support for CUE 3.0 upgrade
If you are a cisco partner, on the GPL there are now new bundle codes to provide packaged phone licenses together with the purchase of a new cme router.
I'm glad to have joined this forum and enthusiastic about the idea.
Cisco has finally posted the latest version of the Call Connector software on their web site. A lot of great documentation has also been added to assist with the installations.

Cisco Unified Communications Manager Express is out and available for download at http://www.cisco.com/cgi-bin/tablebuild.pl/ip-key
This product is available for the Intergrated Services Router (ISR) platform.
It probably won't be available for the UC500 for a couple of months.

Cisco Configuration Assistant 1.6 has been posted.

After a delay of what seemed to be forever, 4.2(7) for the UC520 has finally been posted for download!
