RE: [Sip-implementors] Multiple 2xx
responses
Hi,
But if it is an Options Message , it would receive only one 2xx, even if
considered forking of Options message.

Section 13.1 of RFC 3261 says:
"After possibly receiving one or more provisional responses, the UAC
will get one or more 2xx responses or one non-2xx final response."
My questions are:
1. What is the use of receiving multiple 2xx responses and why does it
happen?
<Response>
Due to forking, UAC can receives multiple 2xx.
</Response>
2. Though an ACK is sent back to all, which one should be considered
finally ?
<Response>
Each 2xx establishes a different dialog
</Response>
3.Can all of them contain SDPs (pbly answer SDPs)?
<Response>
yes. Because each 2xx establishes a different dialog.
</Response>
Regards,
Priya.
