Hi,
We are using FreePBX 14.0.1.20. PBX is connected to GSM gateway Synway SMG4008-8G via SIP trunk.
It was working fine, but two weeks ago all calls were interrupted in 32 seconds. After several updates on PBX outbound calls are fine, but incoming calls still interrupt in 32 seconds.
We have tested gateway with Synway Support team and we saw, that calls released from PBX. Please, find screenshot from capture of one call. PBX’s IP address is 10.10.50.21.
There is part of log
<14>Nov 7 14:29:17 SMGSvr[1030]: 2017-11-07 14:29:17 | INFO1 | Refer: Forbidden Change State(IDLE->IDLE,call=0xe794c0)
<14>Nov 7 14:29:17 SMGSvr[1030]: 2017-11-07 14:29:17 | INFO1 | Call: state changed(CONNECTED->TERMINATED,call=0xe794c0,chid=0,reason=Recv BYE)
Any idea how can I fix it?
