Hi. On our 3CX ver 18 server here we have an issue that is only with calls made to our own DID 10 digit numbers that are attached to our main SIP trunk.
The calls route back properly to the extensions or digital receptionists they are directed to but they get no audio.
All other internal or externa calls work fine. This happens with the app as well as a couple of different models of phones.
3CX sends these DID calls right back into 3CX inbound rules so it doesn't seem to be any external firewall or router issue since the data never leaves the server.
I tried the 'PBX delivers Audio' setting on and off on the extensions and it didn't help. The main SIP trunk also is set to 'PBX delivers Audio'.
Any ideas?
Thank you,
Lloyd
