> Hi - I raised this initially on http://forums.asterisk.org
> but am getting no response there. I hope someone here can help.
> I've just upgraded a local test system from Asterisk 13.0.1 to 13.1.0 and am having problems using pjsip over TCP (same config worked fine on 13.0.1).
> I have 2 virtualbox VMs.
> First VM runs OpenSIPS and rtpproxy.
> Second VM runs Asterisk 13.1.0. chan_pjsip is configured to connect Asterisk to OpenSIPS (over TCP), with Linphone client connected to Asterisk using chan_sip (over UDP).
> Asterisk registers ok with OpenSIPS over TCP on startup, but calls initated by the Linphone client (that should get forwarded on by Asterisk to OpenSIPS and then directed back to the same Asterisk) are currently failing. Call INVITE never gets forwarded to OpenSIPS by Asterisk.

> If I change pjsip.conf (& OpenSIPS) to use UDP rather than TCP it all works as expected.
> Prior to the upgrade I had the same config (excluding the new media_encryption_optimistic=no option) working fine with Asterisk 13.0.1. I don't think I've changed anything in my setup.
> Is this a bug or do I need some additional (Asterisk 13.1.0 specific) pjsip.conf change to get this to work over TCP?
