[SR-Users] ACK and BYE messages uses wrong socket.

Hello,

is .36 address available on the network interface when kamailio is started?

Also, use at least v3.2.3 (the latest in 3.2 series) to be sure you get 
all the fixes since 3.2.0 and this is not related to some issue already 
fixed.

Cheers,
Daniel
