Dear all,
I have a very strange problem :
* external calls work perfectly,
* internal calls between some phones too,
* but internal call between two similar phones don't work !!! (Snom 710)
When we have sound, there are no errors in asterisk. When we do not have sound, there is the
following error :
* [Nov 10 17:51:47] ERROR[21480]: chan_sip.c:28306 setup_srtp: No SRTP module
loaded, can't
setup SRTP session.
This is a working internal call :

I tried many options to disable SRTP but without success :
* canreinvite = no
* canreinvite = nonat
* srtpcapable=no
* encryption=no
* directmedia=nonat
* ...or noload => res_srtp.so in modules.conf
Any help would be GREATLY appreciated !

P. S. We have Asterisk 1.8.4.4 under CentOS release 5.11 (Final)
Please check
http://wiki.snom.com/wiki/index.php/Settings/user_srtp
and make sure the flag is off.
If you install Asterisk with the srtp module, then you need to set the auth-tag to AES-80, but I
haven't played with this option for quite some time.
