[Serusers] SER pstn routing

Dear all I’ve found a problem with PSTN forwarding in the example onr.config. if a CANCEL message is send before a call is setup to a gateway, CANCEL message will not go through and delete the call in progress, so the callee still rings but caller already disconnected. We can add if (method == "CANCEL") { setflag(1); t_relay(); break; }; Then it work properly. But in a t_on_failure configuration, the call still goes to the second route even the CANCEL message is route and forwarded. Is there any thing that we can make the CANCEL message work like it designed? Regards Ray
