Hi,
I'm creating a configuration is for a SIP <> HTTP gateway (performing protocol
conversion) and thus all SIP messages and responses needs to be generated from the
kamailio config file.
I'm failing to create the case where the calling user abandons the session, and thus,
following the reception of a CANCEL a 200 "OK" needs to be sent to this
transaction and later the 487 "Request Terminated" to the SIP INVITE original
session.
On the traces I see:
SIP INVITE (Cseq 1 INVITE) -->
100 Trying (Cseq 1 INVITE) <--
180 Ringing (Cseq 1 INVITE) <--
SIP CANCEL (Cseq 1 CANCEL) -->
200 Ok (CSeq 1 CANCEL) <--
487 Request Terminated (CSeq 1 CANCEL)
Have then tried several options, trying to force the CSeq 1 INVITE but without success.
t_reply_callid("$ci", "$cs", "487", " Request
Terminated ");
t_reply_callid("$ci", "$rm", "487", "Request
Terminated");
t_reply_callid("$ci", "1", "487", "Request
Terminated");
For instance, for the last I get the following log.
6(60226) exec: *** cfgtrace:request_route=[REQINIT] c=[/etc/kamailio/kamailio.cfg] l=705
a=28 n=t_reply_callid

Could you assist here?
