<br>
Thank you for your reply.<br>
<br>
Indeed, Ubuntu only ships with this old version. Upgraded to 16.2. via<br>
PPA. Problem persisted.<br>
<br>
Well, I already mentioned that this is a machine with two physical<br>
interfaces with different routes which on the 'external' side handles<br>
SIP customer registrations and has an 'internal' IC Trunk to a<br>
commercial Voice Switch via private IP Range.<br>
<br>
I had the problem, that some of the packets sent out on the 'external'<br>
side contained 'private' IP addresses in either signaling or SDP.<br>
<br>
So I threw all options I could find into the config to bind<br>
transports, endpoints, media and so on to the corresponding interface ip<br>
address. First this looked good. I had the correct IP in every header<br>
and SDP I expected.<br>
<br>
well setting under transport:<br>
<br>
external_signaling_address=[local IP]<br>
<br>
Assuming this is the own interface IP that would be told to external<br>
endpoints was obviously wrong.<br>
<br>
In the end this caused the Proxy-SBC to believe it was not getting an<br>
OK to it's forwarded registration and discard this session.<br>
<br>
Mit freundlichen Grüssen<br>
