Centrale FastAgi server down

How do you all handle the situation when a centrale fastagi server process(es) are down? AGI(…) prints “Unable to locate host” and the dailplan jumps to exten h.

I’d like to handle the return value and keeping the caller in the dailplan and not to the hangup extension.
Any tips about how to handle a AGI(…) returns -1 condition?

thx
