[SR-Users] [rtpengine] continuous 'Successful STUN binding request from' messages

[Paul Belanger]

I was hoping somebody could confirm the following is a _normal_ log
file for rtpengine. Specifically I am curious of the 'Successful STUN
binding request from' messages are continuously logged.

Are they part of the normal operation or does this indicate some issue
with media? I only ask because I am getting one way audio at the
moment. I get audio from rtpengine however rtpengine does not hear
me.

Chrome seems to be doing this during normal operation. I have no idea
why though, perhaps some sort of keep-alive. You should be able to
confirm successful STUN communication with Wireshark.

I did notice that you're responding to an RTP/SAVPF offer with an
RTP/SAVP answer. That might be the source of your issue.

cheers

Thanks, I have a message in moderation because of an attachment
however I have more info.

It looks like chrome has some keep alive function going, in firefox
they don't come as fast.

I have also noticed, in firefox 31. Audio will establish right away
however in chrome, I need to toggle hold / unhold to get media to be
setup properly. Not sure why I need to do that.

Thanks, I had a typo. I believed I fixed it.

A new piece to the puzzle, if I place the webrtc client on hold then
off, audio is setup properly with rtpengine. However, I cannot find
the reason for this yet. Clearly the "RTP output wanted, but no
crypto suite was negotiated" message is the cause of the issue but not
sure why the hold fixes it.
