What is Call Centric?

[phanhuyen345]

Hello all. Working on my installation of 3cx 11. I am having issues with Call Centric and 3cx communicating and I'm not sure where to start troubleshooting this issue. In 3cx, it shows the trunk is active, but when calling from outside the lan, it is dead air or sometimes the error message from Call Centric. I have followed the instructions on Call Centric website to configure voip provider. I have also disable the STUN server as Call Centric states they do not utilize a STUN server. In it's place I have my external IP Address. The 3CX logs do not show an incoming call and I'm not sure where to find the information from Call Centric to see why the callers are getting an error message.

Any help would be greatly appreciated!

Thanks

Hello @phanhuyen345

The first step in troubleshooting this is updating your PBX to the latest version. Version 11 is very very old and you will have a hard time troubleshooting this as almost no one is running version 11 any more. All guides and templates are based on the latest 3CX version so upgrade your system to V15.5 and let us know if you are still facing the issue.

Since you say you are not seeing an incoming call, I have to assume that, when registering with the provider, an incorrect IP is being used. That may be the result of you not using STUN. If you have a static , public IP, then you should not have to use STUN, but some other parameter may be incorrect.

Does it appear that registration to the provider is successful? Have you spoken to the provider to see what IP they are being "told' to respond to (your location)? It might be a local IP, or an incorrect public IP.
