[SIPForum-discussion] Reg Refresh Register and De-register

[prasanna c]

Hi Sriram,

It is not a MUST to use the same call-id as the initial REGISTER request. rfc says it SHOULD, so that the registrar can process the request from the same UA in the order it was sent by the UA and not in the order it receives the requests.

Also, an UA can unregister a registration done by another UA. (ofcourse, registrar can have a policy to request for authorization for such tasks).

Regards,
Prasanna
