</condition>

I'm not able to check on regexp, as my user ID's match +44-12345678...

And I would like to do one thing if the user exists and otherwise route to my PSTN gateway.

I've tried to just use bridge with both local routing and PSTN calls, but then I try to call my PSTN everytime I call local users.
