reading up and playing around with Asterisk while I've been waiting for an ISDN
card I got on ebay to arrive so I can really get to business. I'd just like to
run my project ideaa by some of you to hopefully get a little feedback. I
aplogize if this ends up being a somewhat long message.</span></font><o:p></o:p></p>

<p class=MsoNormal style='margin-left:.5in'><font size=2 face=Arial><span
style='font-size:10.0pt;font-family:Arial'>In the Marine Corps we've somewhat
recently started using Redcom IGX switches in place of the proprietary (and
ridiculously expensive) switches that we've used in the past (well, and still
do use). This opens the door to all kinds of off-the-shelf equipment that we
can interface with. My goal now is to usefully integrate Asterisk primarily to
provide voicemail and autoattendant feature and probably to demonstrate various
VOIP capabilities. Ideally I would interface via a T1/E1 interface (might as
well use E1 for the extra channels) but since I don't want to shell out gobs of
money for what is at this point still a personal project, I'm opting for ISDN
connectivity. One interface for now will give me two channels but I'll get
another interface when I see more progress.</span></font><o:p></o:p></p>

<p class=MsoNormal style='margin-left:.5in'><font size=2 face=Arial><span
style='font-size:10.0pt;font-family:Arial'>To my knowledge, the Redcom switch
isn't specifically designed to be interfaced with any voicemail systems. However,
it can be set up to forward calls on busy/no answer. This looks like it should
be the ticket. I can set a forward number for each phone to something like
xxxxyyy where xxxx will just tell the switch to follow a specific route to a
group of ISDN channels. Then it'll open an ISDN connection and pass on yyy (and
whatever else is needed) to Asterisk which could be used to identify the
voicemail box somehow. I guess I could set up any type of extension (SIP or IAX
or whatever) and since nobody would ever actually be connected to that
extension, Asterisk would automatically send it to voicemail every time. I
imagine autoattendant could be set up similarly.</span></font><o:p></o:p></p>

very.. limited at this point as I'm sure you can tell. But does my above
thinking seem doable? I imagine I'll figure it all out eventually but any
pointers that might speed up the process would be greatly appreciated!</span></font><o:p></o:p></p>
