Hello,

I'm using ser to forward to PSTN Gatways.

Before the t_relay I put the command:

t_on_failure("2");

So, after a timeout ser goes to:

failure_route[2] {
    log (1, "next gateway...\n");
    if (t_check_status("408|500|503"))
    {
        if (!next_gw())
        {
            t_reply("503", "Service not available, no more gateways");
            break;
        }
    log (1, "gateway changed...\n");
    }
    t_on_failure("2");
    t_relay();
}

This is working very good... if the user doesn't make a hangup.

If caller hangs up, the CANCEL hits SER and the call is cleanly terminated.
SER however continues to failure_route after timeout of the initial
INVITE... ser sends out a new INVITE message to another PSTN-Server... and
the phone rings (with nobody in the line)

Many thanks for your help!
