Yeastar S20 PBX 15 minute outgoing call drop

Postby intplus » 06/01/2020

I have the exact same problem with my Yeastar S20 PBX: all outgoing calls through the Freephoneline trunk is disconnecting after exactly 15 minutes. Surprisingly, I have another trunk on the same PBX with another SIP provider (voip.ms) and calls never get disconnected. The SIP settings (ex: timeouts) on that PBX are global to all trunks. I tried changing the RTP reinvite and the session timers but nothing worked, calls are still getting disconnected.

I also checked the firewall (pfSense 2.4). There is no ALG running and state table cleanup is set to be Conservative. Whenever the call drops I still see the SIP and RTP entries in the state table for a long time after. So this is clearly not the firewall dropping the NAT state.

Like other people reported it in this discussion, I had a few random call drops before but this situation happenning at every outgoing call really started somewhere in March 2020. Any one has an idea?

Freepbx/Asterisk users in the thread you originally posted in resolved their issue by using type=peer and canreinvite=no

I've split the topic since they've resolved their issue and yours involves Yeastar S20 PBX.

You might want to see if there's a firmware update or newer Asterisk version you can use.

pfSense doesn't have a SIP ALG unless you've installed siproxd.
