I am looking for some advice technical assist with an issue that we are having with our asterisk based PBX.
We have been running an asterisk setup on our internal network for several years with almost no incident. We have two ISDN lines that connect through a B410 digium card to a wazo based asterisk box.
Due to us now needing to work remotely we are running into issues. Everyone has their own physical SIP based phone at home that connect to our internal work network. This network has a public IP so there are no issues there. We have also set it up with the following IP rules:
5060:5160/udp ALLOW [login to view URL]
10000:65535/udp ALLOW [login to view URL]
I have got the phones mostly working but I seem to be running into intermittent issues. These issues are as follows:
- Some phones randomly disconnect and then seem to not reconnect properly.
- Sometimes when you dial out you cannot hear the ringing and when the callee picks up there is no audio either way.
- Calling extensions you cannot hear audio either way.
I want to know how I can potentially fix these issues and whether I should be using STUN (I have tried enabling this on the phones but it didn’t seem to make a difference), or how we can ensure the connection is consistent.
I can provide access to the WAZO UI and provide screenshots of the phone’s settings.
When the phone randomly decides to connect the audio actually work really well.
