HI Klaus,
i'm testing SER to redirect the calls started with 00 to natrelay.deltathree.com because my sip server is behind NAT, the scenario is like this:
X-Lite --> SER --> DeltaThree --> etc .... |_________| NAT
X-Lite has 192.168.0.1 SER 192.168.0.2
and as i've told you i can send a call CANCEL it but i can't send BYE to stop a call that is already in progress
Here is my config.

Hi Nikola!
Without message dumps its impossible for us to solve your problems!
regards, Klaus

I'm trying to setup SER to route my outgoing calls to DeltaThree's servers. So far i'v managed to forward the calls but my problem is that if a call starts somehow i can't record route the call and my UA is not sending BYE to the servers, so i'm getting billed more than i talk. For call duration of 0:10 i can see 1:45 on deltathree servers.
If you manage to work something out let me know.
