I am trying to send a SIP CANCEL message using the t_uac_send() function from the tm
module to cancel an INVITE message that was sent previously.
`$var(requestHeaders) =
"Via: " + $var(via) +"\r\n"
"To:
sip:1010@172.16.100.76:6060;tag="+$var(tt)+"\r\n"
"From:
sip:rvrbt@172.16.100.76:6060;tag="+$var(ft)+"\r\n"
"Call-ID: " + $ci + "\r\n"
"CSeq: 1 CANCEL\r\n"
"Max-Forwards: 62\r\n";
t_uac_send("CANCEL", "sip:1010@172.16.100.76:6060", "",
"",
"$var(requestHeaders)",
"");`
I am encountering an issue where an additional Via header with a newly generated branch
parameter is being added to the top of the headers.
This behavior causes the CANCEL request to not be recognized as part of the existing
transaction and I get "SIP/2.0 481 Call/Transaction Does Not Exist"
Logs and Debugging Information:
Include relevant logs here, such as the generated CANCEL request and the 481 response.

Have you tried to use the tmx t_cancel_callid(callid, cseq, flag) function? There have
been reports that the t_uac_send(..) function is not working for CANCELs in the past.

Have your peers meetings been completed? If transactions were not
conversational, why not use stateless SIP messages to respond to INVITIE
requests?
In these cases, it is better to use sl_relpy to send appropriate messages.
With best regards.

Yes, It works. Thanks!
