Re: [Sipping] how to response the offer

Hello SunYongGuang,

A should consider incoming SDP as new offer and answer appropriately, quite likely as you mention the offer has not changed it would send a 180 or 200 OK response with same parameters as negotiated first time.

In any case A should not ignore  the incoming re-invite as that would cause B to terminate the session, Section 14.1 UAC behaviour of RFC.

Hope it helps.

Regards,
-Tanu.

Dear All
 
   I have a question about How to respond the offer , the scenario is as following
 
A call B , and the offer and answer is ok , after a while , A receives a B 's REINVITE which includes the same SDP as it just answered before
 
now, How does A respond it ? 
 
does A  must respond  the B's new offer  with   the same SDP as the offer it sent previously?
 
could you give some advice ?
 
Thanks
