One-way RTP Stream mid-call??? Polycom 321
Hello, I have a strange problem where the RTP stream will stop mid-call. Only affecting Polycom SoundPoint IP 321 Phones. I have updated the phone to the latest firmware (4.1.1.0731)
At first the RTP stream is lost for > 30 seconds the call was disconnected.
[2018-02-15 16:16:29] NOTICE[6591]: chan_sip.c:29402 check_rtp_timeout: Disconnecting call ‘SIP/5524-00001a47’ for lack of RTP activity in 31 seconds
I modified “RTP Timeout” in “Asterisk SIP settings” and this stopped calls disconnecting.
I am using FreePBX ver. 13.0.191.11 / Asterisk Version: 13.12.1
When I debug the RTP stream I get
