Hello, We have a concern with a client. We do not manage his internet connection and can not act on it. All ports are open to the PBX from LAN. The problem: If we keep the defaults settings, the phone does not register. It is impossible to emit and receive any calls. If we change the parameter "Outbound Proxy" directly on the phone's web interface, and switch from "transport=tcp" to "transport=udp", everything works perfectly ... until the next reboot of the phone. Do you have an idea to fix this parameter UDP instead of TCP? I can not find the option on the pbx and change the outbound proxy each electrical outage or when phones reboot is not acceptable for us ... In advance thank you, and have a good day! PS : PBX and phones are up to date
