You will need to play with the fr_inv_timer after the call is forwarded. You can achieve this by using avps: http://openser.org/docs/modules/1.2.x/tm.html#AEN249
Ack. I don't like AVPS :D Further, as you all may have realized, I was trying to do call forward on busy and not CFU :D ...
As you see I'm not using fr_inv_timer_avp but I would think doing something like
modparam("tm", "fr_inv_timer_avp", "$avp(i:99)")
And then in the failure route before t_relay() $avp(i:99) = 120;
And it did :D
My next question of course becomes, what happens when this timesout?! As I said initially I only get one call to failure_route, so apparently when failure_route fails it just dies?
