[Serusers] Failover Forwarding

[Jan Janak]

Do the following:

# Send to PSTN
route[5] {
	rewritehostport("GW_IP_1:5060");
	consume_credentials();
	append_hf("P-Hint: GATEWAY\r\n");

	t_on_failure("1"); 
	if (!t_relay()) {
		sl_reply_error();
		break;
	};
}

failure_route[1] {
	rewritehostport("GW_IP_2:5060");
	append_branch();
	t_relay();
}
				
  Jan.
