I need to add a second CME to an existing setup and I am looking for some tips sinced I have never setup a multi-CME system. From what I can gather I will need to use a dialplan pattern but it is not clear why this is needed.
The first system uses extensions in the 2xx range. I plan to use 3xx extensions on the second CME. So if I create a dial-peer that matches 3.. on the first system and a dial-peer that matched 2.. on the second they should be able to call themselves, no?
Is it that simple or am I missing something?
I dont see why not. As long as the ephone-dn config has the name mentioned for that extension's user, then the other CME system should get it to display on the ip phone. Do let me know if you have any additional questions.
