[Kamailio-Users] fr_anything_at_all_timer.

[Klaus Darilion]

Hi Alex!

Not sure what you mean:

For detection if the gateway responds at all use fr_timer. I set it to 2 
seconds. If there is no reply from the gateway within 2 seconds, the 
failure route will be executed. If there is a reply (e.g. 100), then tm 
module changes to fr_inv_timer which I have set to 120 seconds.


regards
klaus
