The INVITE from w.x.y.z:44308 -> a.b.c.d:6060 is not given. That's the one that is needed in order to match the CANCEL, which comes from w.x.y.z.
Can you provide it? Cheers, Daniel

Hello,
do you have a pcap with all messages for such call (invite, replies, cancel)? It is important to see if the transaction matching elements are properly set.
In general, the rule for cancel is to be sent in the same way (with the same elements) as the invite, because cancel is not a standalone transaction, it must match the associated invite one. Cheers, Daniel

after couple of tests, it is still hit and miss, sometimes it matches, sometimes it does not.

thanks alex, will test this out further but looks good at the moment any idea why it is not matching when RURI has the port if i only use t_check_trans() and relay?

Try this instead:
route { ...
t_check_trans(); ... if(is_method("CANCEL")) { if(!t_relay_cancel()) sl_send_reply("500", "Internal Server Error"); exit; }}
