Hi,
The scenario is:
When Callee receives RE-INVITE having presentation offer,
he can reject the offer. If we don't set our sdp answer using
pjsip_inv_set_sdp_answer(), then pjsip sends 488 response by itself.
I want to set a 'WARNING' header in 488 response stating
specific reason for rejection. But it seems that we can't send a response
by ourself as API's used to send response need pjsip_rx_data as one
of the argument. In on_rx_offer callback we get only
pjsip_inv_session and pjmedia_sdp_session as arguments.
Can anyone guide me?
-thanks
