> Key: ASTERISK-28966
> URL: https://issues.asterisk.org/jira/browse/ASTERISK-28966
> Project: Asterisk
> Issue Type: Bug
> Security Level: None
> Components: Channels/chan_pjsip
> Affects Versions: 16.10.0
> Environment: ubuntu 18.04, docker, asterisk 16.10
> Reporter: Robert Sutton
> Assignee: Robert Sutton
> Labels: fax, webrtc
>
> we had rtp_symmetric set to "no" on the trunk endpoint
> It seems that asterisk and our up stream sip provider got into a feed back loop as can be seen below.
> This is just a small snippet of this, in 90 seconds this line was logged 600+ times across 3 channels.
> This was detected because the system was failing to bridge channels, it may not be the cause of failing to bridge, but either way it is a problem.
