I have no idea what your saying. It works fine as is. Why would you have a "partial" message under the context of TCP? TCP handles this where UDP does not.

Hi.
I had seen reTurn's source code.
and i found it there was no stream integrality check.
it means that e.g. a tcp stun packet "STUN MESSAGE".
when there is no delay.the server will work well.
but when there is a delay.the server may be receive "STUN M".
that will cause the server can not work.and response bad request error.
so .i do not think reTurn can work well.
Am I Right??????

xutm, I'm not sure what your asking. Compile reTurn with your own configuration and certificates and use it.

Hi twok48bit ,
Do you have write any documents about resiprocate STUN/TURN server works with pjsip? Can you show me some if u have or give me some ideas about this ? I am working this but without any ideas. Thanks in advances.

The pjnath library implements ICE and therefore it ships with a STUN and TURN server. Also I the resiprocate STUN/TURN server works fine(it is compliant) with pjnath/pjsip.

hello.
I have a stun/turn server myself.
if you want to test icedemo.i can send it to you.
of cource no source file.only binary app.
If you find any stun/turn server that has full implement and more useful .tell me too.thanks.

Subject: I need a stun server
Hi,
To test icedemo.c, I need a STUN/TURN server. In your FAQ, it's said
"As of version 1.4-ish, ... ... and now that there is one available,...... "
What is the "one" here? Is it ReTurn (http://www.resiprocate.org/ReTurn_Overview)? Has the compatiblity been tested?
Thanks.
