I have a customer with three sites. They were all independent offices, with their own UC520 units in each office. Not sure why it was setup this way, but I have now inherited this. The problem I am having is with changing the IP address of the service-engine interface of each UC. I want to create a VPN tunnel between the three sites so they can dial by extension to each site. But everytime I try to change the IP range for the service-engine interface, it reverts back to the 10.1.10.0 block. I can't forward the calls if this is happening, because the IP's cannot be the same when setting the session targets in the dial-peers. Has anyone else run into this, or can this even be done? I am not sure why I can't change the IP block on each of the UC520 units.
What are you doing when it
What are you doing when it reverts back? If you are using the CCA after you have started customizing, then that could be your problem. As soon is you get into custom configs you should keep the CCA as far away as possible.
What you are doing is very possible. Use the CLI to change the IP.
All changes made using CLI
I am changing the IP's in the command line. To be honest, I am new at configuring UC500's, and dont even understand the CCA. I have more experience with the CLI configuring other Cisco products, and I have made all my changes in the CLI on this device.
Once I change the IP addresses on the loopback interface, the service-engine interface, and the route to the service-engine interface, I can't access the CUE GUI. I then restart the CUE service-module, and the ip's automatically revert back to their original configuration. This becomes a problem because all three sites have the same IP's for the CUE. I can change the IP's for the Phone and data VLANs no problem. If there is a way to forward the calls to the remote offices using the data or phone IP's, and still be able to access the AA and VM that would be fine too. Thanks for all the responses.
Are you saving writing the
Are you saving writing the config? Check the ACL's (access-lists) on the interfaces and make sure the allow your new network or just remove them.
Sorry, should have clarified.
Sorry, should have clarified. I have changed the ACL's and have written the config to flash before restarting the CUE.
IP scheme
In the scenarios that I have set up, the dial peers for each site point to the vlan 1 IP addresses.
Once the remote system receives packets it processes them via it's dial peers to go to the correct extension.... the problem that I had was when the user at the remote site was unavailable and the remote system tried to pass it to the local CUE...
I did resolve the issue I had though... it was to do with the transcoding.... I was using G729r8 between sites, but the CUE uses G711 so I had to configure the transcoding parameters and codec preferences so that each system could pass the G729r8 packets to CUE as G711 without disconnecting the call...
I will try and dig out the config that I used as it was a while ago that I did it, unless someone else beats me to it.
Hi, Have you had a look
Hi,
Have you had a look at

I did take a look at the the lab, but the lab indicates that this configuration is done only when there is no VPN involved. In my case unfortunately, I have IPSec VPN's interconnecting all sites, so this scenario will not work for me.
