I have just built a new 3cx installation V14 on a new server 2012R2 box ready for the upgrade from V12. The V12 server 2008 has run fine for the last 3 years but thought it time to go to V14 and as a result to minimise downtime decided to build a new server for it, the install went fine and select multiple instances as we plan to use this for customer systems in the future. We restored our config to this server from the V12 backup and all went well. Last night we failed over to the new server to test and we had no calls inbound and the two external siemens gigaset handsets stopped connect as well. Now I have not looked into why the two extensions will not register as at present the SIP trunk will not accept calls, nothing shows in the logs on 3CX but what I have noticed is that on the V12 box I can telnet to 5060 but on V14 I can't. I have disabled windows firewall but it is still blocked. We use TTNC for our inbound SIP which I know is not supported but has worked great for the last 3 years. All we do is enter our [email protected] and it seems to send the traffic in. In V12 we had to enter the username and leave the password out on the SIP trunk but this has always worked. We have now failed back to our old V12 whilst trying to find ideas on how to get at least calls inbound. Any suggestions ? should telnet to 5060 work or am I looking in the worng place.
