  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");
