Hi,

I am trying to figure out how to interpret response code 408 in a 
failure_route block.  It seem that there is a couple of different cases.  If 
the code means that a PSTN gateway is not responding (the tm's fr_timer has 
expired), I want to try another PSTN gateway.  On the other hand, if the 
code means that the user is not responding (the tm's fr_inv_timer has 
expired), I want to stop trying and forward the code to the UAC.

How can I tell what response code 408 actually means?

Thanks!
Dmitry
