[Serusers] Signalig through 2 proxies

Hey There.

The BYE request is sent to the GW. And it is sent to the right port/IP. 
Actually I thought that the problem was something like it, so I start to 
capture any traffic from/to GW and nothing appears.

Another weired fact. When the call is finished by caller (ATA Terminal) 
the message is send with authentication information and the GW response 
with OK (normal call tear down). But, if I wish to finish the call by 
using (1st) proxy, the GW never response it (only after 90 seconds - 
default behavior of PSTN).

Thanks in advanced,
