Subject: [Sip-implementors] Doubt in REFER method
Hi all,
I need to know if REFER method can be implemented without getting a NOFITY
request. RFC 3515 tells that REFER implicitly generates a subscription.
We know that the REFER request contains a Refer_To header telling the
trasfer target. The Transferee UA willing to contact this transfer target
will return a 200 OK if that target is reached or a failure response if that
target could not be reached. This response will be announced to the
Transferer.
If this is the case, what is the purpose of the NOTIFY request?
Thanks in advance,
B.Suganya
