Hi,
I’ve been using FreePBX successfully for quite a while now, initially using a single server on a subnet of our main network.
With no changes to the network (I’m the network admin!)one day we couldn’t hear any audio on both outgoing and incoming calls. My assumptions were the router between the main network and the subnet.
By placing a FreePBX server on the main network and connecting an IAX2 trunk between them, we’ve now had 7 months of problem free running until…
Yesterday morning, again with no changes to any configurations, we’re back to one way sound again.
Config is
Phones: Cisco7940
Internal trunk: IAX2
External trunks: Sipgate SIP
ISP: Sharedband
The SIP provider and ISP deny any changes to their systems that would affect me. Now I’m stumped.
So my question is, where do I start to troubleshoot a connection that has worked for 7 months.
Any help in troubleshooting this much appreciated.
many thanks
Trevor
