SIP REGISTRATION ISSUE in 3g network

Hi All,

In 3g network client is sending REGISTER Request multiple times to server. After 3 Register packets server respods with 200 ok. In that case the contact URI field is different in server side so incoming call couldn’t land on this user.

We do have TURN server supportability. The port in contact URI is different in server.

Please help me in this problem.

Thanks,

Vimal.
