There are several parts of the config where this type of problem can be checked
and caught. An easy one, provided you aren't running an asterisk on the same
IP that talks to opensips or something, is this source ip and request domain
check
if( $si == $rd )
{
xlog("L_INFO", "Rejecting message that seems to be looping\n");
sl_send_reply( "483", "Something wrong in SIP Message - created
loop" );
return(0);
}
Another thing to check in CANCEL and ACK handling is can message be routed
somewhere from the message headers or is it part of an existing transaction
if( (!loose_route()) && (!t_check_trans()) )
{
if (isflagset(1))
xlog("L_INFO", "not forwarding $rm with
debug turned on for $ci \n");
return(0);
}
If you have these and still have a problem it's going to require a lot more
information about your config and some ngrep traces to nail down. For me
anyway. Someone else might have some more thoughts just from past experience.
