Hello Alex,

Again thanks.

I'm using that calculation to, when receiving a 180/3, if it comes in too
quickly (i.e. 100ms) i cancel that call, and send a 480 the the A leg.
I haven't found way of doing this, is this possible at all? I trired
setting a very low t_set_fr(10,10) (0 means set the default), but that's
not working...

Is there a way of doing this?

Thanks!
Regards,

David Villasmil
