I have 3 Cisco 7961G phones with 9.4 SIP firmware. These phones previously registered to an earlier version of Issabel with asterisk 11
I have the config files used in previous installation, with no editing and configured the SIP extensions to these files. The server IP was also conformed to the IP in the files.
Asterisk13/Issabel4 never even shows a registration attempt with a SIP debug . Wireshark clearly shows the registration attemps and to the correct port. Grandstream devices register fine.
