asterisk users - Jun 2006 - Determining if extension exists

All,

Is there a way I can perform a lookup to see if a given extension exists within
a given context, on the local system? I could call Dial() and check the result
of $DIALRESULT, but I'm thinking there should be a better way.

Note, that I don't want to use ChanIsAvail(). That's only for
determining if endpoints, ie phones, are registered. It doesn't seem to work
with extensions.

I am (trying) to use DUNDi. I'd like to perform a local lookup first (seeing
as though DUNDi never returns the local system as a path, even when it's
valid) before dialling the number via DUNDi if it isn't available.

Doug.

Worked it out...

ChanIsAvail(Local/${EXTENSION}@${CONTEXT})
