[Serusers] Setting timeout in SER

[Marian Dumitru]

Hi,

If you want to change the global value for the invite timeout, you can 
use the tm parameter "fr_inv_timer" - note, this will affect all your calls.

If you want to change the behavior only for calls going to PSTN, before 
relaying to GW do:
	avp_write("i:10","fr_inv_timer_avp");
where first param "i:10" gives as integer the timeout value - note you 
have to load the avpops module.

To override the default reply 408 Timeout generated by the invite 
timeout, set a failure route for calls going to GW :
	failure_route[x] {
		if (t_check_status("408")) {
			t_reply("503","Service Unavailable");
		};
	}


Best regards,
Marian
