Hi Brett,
Earlier also, I have gone through behavior described in RFC 6337 but still not
clear about the behavior.
RFC 6337 says:
5. PRACK Req. (**) 200 PRACK Resp. followed by new offer
OR termination of dialog
If offer in PRACK is rejected then UAS should respond with 200 OK followed by
BYE(i.e. termination of dialog) or new offer.
Let say, we opt for terminating the dialog.
But, sending BYE would terminate the call where offer answer is already
negotiated.
Is this the correct behavior to implement or should we reject only PRACK and
dialog should not get impacted?
Regards,
Kamini
