[Serusers] Requests coming on the source port instead of contact port

[mahesh]

Hi All,

I am using SJPhone application on a windows XP machine to register with the 
IPTEL.org proxy server.(publicly available) In this Register request which 
is sent to the server, the contact port is different from the source port. 
Now the SIP invite requests coming to this machine are being sent to the 
source port of the register request, instead of the contact port of the 
register request. IT WAS EARLIER COMING ON THE CONTACT PORT.

Was any change done in the proxy server recently which is causing this 
behavior?

Thanks
Mahesh
