[Serusers] SER + NAT

[Iqbal]

try ethereal or negrep to trace what is happeing, to see if the message 
are being sent by the caller. and if ser is receiving.

Also in xlite, you can start a debug log, this will show you all message 
transactions, run this on both xlites, and see if they are sending and 
receiving a BYE.
