Summary:                    "empty" overlap-dial-in doesn't work
Description: 
Some PRI callers (like the ancient telephone system we want to replace)
always send an empty SETUP message, and provide the actual number later.

Unfortunately, pbx_find_extension() is set to return NULL if it sees an
empty extension, thus preventing the call from ever completing.

I noticed the problem with DAHDI, but I suspect it's not limited to that.
