[Asterisk-Users] Dialing an outside number -- QUESTION --

[Steve Murphy]

Hello--

I'd like to do a little processing on external phone numbers from within
the asterisk pbx. Fairly simple stuff, but... devilishly hard to make it
work so far!

1. I'd like to dial 9 to get an outside line.
2. If the number dialed after the 9 is 754XXXX, I'd like it to go thru
unmodified. It's the only local number available here.
3. I'd like all 1 XXX XXX XXXX  numbers to go thru after the 9,
unmolested.
4. After the 9, I'd like all other 7 digit numbers to be dialed
1307NXXXXXX.

Simple enough, right?

I wrote up the following:

[outwork]
ignorepat => 9
exten => _91XXXXXXXXXX,1,StripMSD,1
exten => _1XXXXXXXXXX,2,Dial,Zap/2/BYEXTENSION
exten => _9754XXXX,1,StripMSD,1
exten => _754XXXX,2,Dial,Zap/2/BYEXTENSION
exten =>_9NXXXXXX,1,StripMSD,1
exten =>_NXXXXXX,2,Prefix,1307
exten => _1307NXXXXXX,3,Dial,Zap/2/BYEXTENSION

[workext]  ;; the active context for an internal extension
include => outwork
... (other extensions, but not 9)
exten => t,1,Congestion
exten => i,1,Congestion
exten => o,1,Congestion


And it doesn't work, and neither do maybe a dozen variants.
I split the 3 groups up into different contexts, I remove the second two
StripMSD commands. I sequence the  priorities from 1 to 7. I tried
setting all the post-StripMSD commands to priority 2, I... and on and
on, including combinations of the above, and the best I can do, is get
the first one to work. I can dial 91<10 digits>, and the <10 digits> are
sent out to the phone company, and the phone rings out there. All the
rest might have me wait some seconds, and then I get the congestion
tone.

And, on top of everything else, the moment I touch 9 on the extension,
the dial tone goes away. So IgnorePat doesn't work in this situation,
either.

Checked the documentation for dial and stripmsd, and none of the
examples cover anything more complicated than a single pattern.

What am I missing?
