Hey all,

Reviving this thread just to see if anyone has thoughts here?

I've tried digging through the source and can't seem to find where the re-opening of auto_adjust happens during a re-invite. As an aside bug (I'll report in JIRA) - it looks like the always_auto_adjust RTP bug results in very choppy audio.

That said, I don't need always_auto_adjust, as I'm fine with sending a re-invite when I need this to happen. It just doesn't seem to be working. Is there something else that needs to be set or is this also a bug?

Best,
Colin

Is this the case even when the RTP IP in the SDP doesn't change? I'm seeing successful re-invites being processed with no auto adjust happening afterwards. I see:

2016-05-13 21:28:24.216684 [DEBUG] sofia.c:7614 Processing updated SDP

Indicating that FS did receive the SDP in the re-invite but nothing else about RTP auto adjust afterwards. This is on FreeSWITCH Version 1.6.7-14-d38d065~64bit (-14-d38d065 64bit) running on Debian 8 x86_64.

Thanks for the response.

Best,

I have mobile applications running behind NAT. When their reachability changes (and the device's local route updates), I want to automatically switch the RTP stream to the new address/port combination.

I've tried using the RTP ALWAYS_AUTO_ADJUST bug, but that results in very choppy audio. I also don't really need it, as the only time I care to perform RTP auto-adjust is after an invite session. For this case I can safely assume that the client will send a re-invite when its address changes. Is there any way to perform RTP audio adjust only on a re-invite?

Using STUN doesn't seem right for two reasons: 1) on its own it can't solve this problem (even if it determines the external IP, the port is still wrong). 2) it results in issues on FS "Invalid STUN/ICE packet received 20 bytes"

Would appreciate any help.

Best,
Colin
