how do you know that there is no BYE? Do you
capture the network traffic
on the proxy and on the client side? Use ethereal to verify if there are
differences to the BYE and CANCEL messages.

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

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