The basic problem is that they don't think they can program this loopstart 
circuit to
send the virtual phone number (AKA the DNIS) at all.  Yes, I did do a lot to 
clue
them in to what's required but in the end, there seems to be that roadblock: you
can't do a substitute for the CID number, which sounds like it would be the 
ideal
solution for the loop lines. Hmmmm....I should probably ask about the DTMF after
the call is answered though, just in case they never thought of that. So those 
"after"
digits would dial the virtual number's extension, right? Hence the delay after 
the call
comes in so that the digits can be picked up.  I'm not sure how reliable that 
would
be (see last paragraph). Based on my wife's experience using a calling card, I
would think that the  tones would get lost sometimes.

We (myself and the Aliant sales rep) are thinking now that ISDN lines will have
enough flexability to do the job. They are certainly a step up from DID and not 
that
much different from Centrex when you think about it.  I would appreciate any
opinions on 4 port ISDN cards.

As for Asterisk experience, I doubt it. But I can ask again.  Aliant has let a 
lot of
their good people go.

BTW (opinions please) is Asterisk for Business stable enough for a critical 
service
application or am I out-to-lunch here?  Another project has come up and I'm
thinking of using ISDN for incoming lines and an OpenSwitch6 FXS/FXO card for
connecting analog phones and lines. * does the recording and call transfers. I 
was
hoping to keep it simple but it looks like we will have to have a screen pop 
added
on also.  Could be a tall order, what?
