Dial outbound zap with large local calling area


#1

I have 60+ local call exchanges that I’d like to route outbound to a
TDM400 fxo on the pstn.

Within the dial plan, can a gotoif reasonably handle a sizeable or’ed
search pattern, like:

exten => _NXXXXXX,1,GoToIf([_123XXXX|_456XXXX|_789XXX|(many more]?2:3)

or a big global

DOLE=_123XXXX|_456XXXX|_789XXX|(many more)|_987XXX

exten => _NXXXXXX,1,GoToIf($[${DOLE}]?2:3)
exten => _NXXXXXX,2,Dial(${ZAPTRUNK}/${EXTEN})
exten => _NXXXXXX,3,Dial(${IAXTRUNK}/${EXTEN})

obviously I could list them individually in the outboung dial plan. A
variable, or read-from-a-file would be nice to have, I could use an
include with the variable and values in it.

Other suggestions?

Thanks, Andy

Answering my own questions, I could not get gotoif to parse or’ed strings
quite the way I wanted (hoped), thus the result follows for now.

I whacked around a half dozen scenarios - one can do it any way they
like, even as ugly as the following - and maybe this is ugly and labourious
to the cpu, but it stuffs all the local exchanges into one variable, or an
include file, or a db table for access, which makes it a bit easier to
manage, although you have to keep up with the code below, too. I could
(maybe) work in some auto-incrementing $dole locations with another if
and goto, until $dole="". I quite probably have missed an easier way…
