[Serusers] multiple contact entries automatically....

[Klaus Darilion]

Use ngrep and verify the REGISTER messages. If the NAT port changes can 
have mainly 2 reasons:
  - The NAT bindind expired and a new binding is created: Try to 
increase the NAT-ping or the expires value.
  - The SIP client changes its local SIP port: Throw them away and buy 
other phones :-(
