My client has observed that some calls (the number is increasing) lose one way audio (most of them outgoing audio) after 30 minutes of the call.
Today, after a pair of 1-hour calls with no problem , I got another one call, that after 30 minutes it got no audio from client, but the call was still active and my client was able to hear my voice, so the call got mute with outbound audio only (from client perspective).
Do you have any idea ot a possible solution of this kind of problem ??
I ran into a similar problem where after exactly 30 minutes the call would drop on our CME router. It was a problem with the REINVITE between CME and our SIP provider just like Logan mentioned. Here is what we did to fix it, you may have some luck with this but might have to tweak it depending on what your provider is looking for:
After one month of testing, the ISP found one equipment on SIP cloud sending a keepalive which did not receive any acknowledge from its remote peer. After 30 minutes without keepalive remote peer cut audio from customer to PSTN. We are asking more information about the solution.
