I'd capture some SIP traces and see if there are useful differences in
the calls that don't go through, then work forward from them to getting
that info into your dial plan.

Alternatively, you could ask Ateus for some support, the gateway
must _know_ the hangup cause was congestion, it should just be
a matter of it telling you !
