Anybody know what could be so significant in the setup of 3cx SoftPhone ? I can use it successfully at a remote location - but getting a handset to work is ridiculous. The remote phone registers fine and can make and take calls. I have two way audio going - but any calls I make from the remote extension (Yealink T22) dies after 32 seconds - every time. The local side realizes this and terminates the call as well. If the remote side hangs up before the call dies - the local side doesn't know about it until the 32 second mark. This is when I am in TCP transport. When I change to UDP Transport the call lasts longer than 32 seconds but can only make outbound calls. Inbound calls do not work - the remote phone rings and the person answers but the local side shows still calling. I know everyone has put in their two cents on this for me before - but there has to be a key factor missing as the soft phone works all the time.
