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
