When I call using my voip provider I can hear the sound from the person on the POTS line but they can’t hear me. If I restart asterisk the first call is fine, but after that the problem shows up again. I would tend to think this is my problem and not the voip provider because restarting MY server fixes the problem.
Calls within my system (extension to extension) work just fine. I am willing to provide any configuration files needed. I would really like to resolve this issue.
The problem is intermittent. This is most frustrating. Without restarting asterisk I placed two external calls with another extension. They both worked. The third did not, again only one way sound.
I’m not sure what you meant by that so I’ll just post my sip.conf general section:
port = 5060 ; Port to bind to (SIP is 5060)
bindaddr = 0.0.0.0 ; Address to bind to (all addresses on machine)
