Function Documentation

int nta_msg_ackbye	(	nta_agent_t *	agent,
		msg_t *	msg
	)

ACK and BYE an unknown 200 OK response to INVITE.

A UAS may still return a 2XX series response to an INVITE request after the client transaction has been terminated. In that case, the UAC can not really accept the call, but it may send a ACK request to UAS followed immediately by BYE using nta_msg_ackbye(). The function does not create a transaction objects, but just sends the ACK and BYE request messages according to the Record-Route and Contact headers in the msg.

int nta_msg_mreply	(	nta_agent_t *	agent,
		msg_t *	reply,
		sip_t *	sip,
		int	status,
		char const *	phrase,
		msg_t *	req_msg,
		tag_type_t	tag,
		tag_value_t	value,
			...
	)
