sorry but i face the same problem and i really get confused, my CME version is 7.0 , so if we suppose that my CME IP address is : 192.168.11.1
so what is the url exactly should be?
thanks in advance
If you monitor the config file being sent to the phone when it registers, you'll find which file was used. Locate that file and check the url in it. The url should be the default one in most other phone config files in the router, but what happened to me was that the file being sent to phone didn't have the url in it. So making sure the correct config file is used is the key.
