Hello, I'm trying to use the function t_uac_send inside a failure_route as described in https://kamailio.org/docs/modules/5.3.x/modules/tm.html#tm.f.t_uac_send to send a CANCEL out. Although the documentation says "it can include From/To tags" i was not able to get the from tag provided to be used. Another random generated one is used. I've tried the following format without success: t_uac_send("CANCEL", "$ru", "", "", "From: <$fu>;tag=$ft\r\nTo: $tu\r\nCall-ID: $ci\r\n", "") t_uac_send("CANCEL", "$ru", "", "", "From: $fu;tag=$ft\r\nTo: $tu\r\nCall-ID: $ci\r\n", "") t_uac_send("CANCEL", "$ru", "", "", "From: bob@kamailio.org;tag=2w3e\r\nTo: $tu\r\nCall-ID: $ci\r\n", "") In the last one which is copied from the documentation that is how the
From header going out looks like: From: <bob@kamailio.org;tag=2w3e>;tag=3393f0703fb0ccaca74109ff37de39f5-36d71ef0
Any tips on how to get the From tag passed to the function to be used? Thanks, Joao Arruda

I have a follow up question on this. Now that the From tag works as expected I'm not getting a "400 Bad Request" for the CANCEL being created by the t_uac_send inside a failure_route anymore. But now i'm getting "481 Call/Transaction Does Not Exist" Since the from header and tag, to header, Call-ID and CSeq all matches the original INVITE I suspect that is because the Via header branch parameter in the CANCEL doesn't match the one from the original INVITE. There is a way to make it matching? Regards, Joao Arruda Em qui., 19 de nov. de 2020 às 17:40, João Vitor Arruda <joao.arruda@gmail.com> escreveu:

Thanks Daniel, I've tried t_cancel_callid function but it didn't work in this case. I'm not trying to cancel a local generated INVITE. Let me explain what i'm trying to do and maybe you have some additional suggestions. This is a case of serial forking controlled by kamailio. The original received INVITE is sent to the first destination (in an array of destinations to be tried out) and if it replies with 486 or we have 408 on branch timeout then the next destination is set to $rU and we t_relay() again. This will both send the new INVITE out and the CANCEL to the previous target which is working fine. But to workaround a specific issue with one of the destinations identifying two sequential tries as a looped request I would like to first send the CANCEL for the previous INVITE, wait some seconds and then send the new INVITE out.
