Hello Jeremy,
We have implemented HA systems in the past for numerous clients,
call centers, etc, where reliability matters. We can definitely offer
you a bid on this, but I would like to speak with you a bit first to
nail down the requirements. What would be a convenient time and number
to reach you?

I have a ton of Nortel MICS/CICS phone systems and am looking for an
easy way to integrate them.
Two questions arise:
1. Is it feasible to use asterisk as a Man in the Middle for a
T1 PRI system? The idea is to intercept outbound calls from the
Nortel PBX and redirect them via VoIP to another asterisk box at
another branch transparently(thus saving the LD cost). Otherwise I'd
pass the call on to the T1 for outbound processing. Our Nortel is
already PRI equipped, the PRI would just come from the Asterisk box
instead of the Telco directly.
2. Is it feasible to use asterisk as a Man in the Middle for
Analog lines? I'd be using anywhere from 4-12 lines depending on
location size. I'd like to do the same feature as above(intercept
outbound calls and redirect them using VoIP if they are inter-office
calls.
a. I'd also like the VoIP trunks to be used for outbound calls
in the case of PSTN downtime or busy. For example, all 4 outgoing
lines are in use, person 5 wants to make an outbound call and it gets
redirected to one of my T1 offices. I'd attach their outbound caller
ID to make it appear as the call came from that location.
My inevitable hope is to reduce my analog presense in smaller
communities to 1 primary Line for 911/emergency calling, and to get a
published presense in the community. I'd then beef up my T1 locations
to handle more VoIP based calls. Currently we're using on the order
of 30k minutes a month of LD just intercompany, about 10k external
(IntraLATA).
I'd also like any insight or suggestions on uptime. We're a
healthcare organization so 5-9's is what we'll require.
Any suggestions on hardware configs(or better yet, Bids!) would be
appreciated as well. I don't need VoIP capable phones yet, but if the
system works well enough we'd probably startup our next
location(averaging 3-6 per quarter) with a pure VoIP system with
Nortel fallback(again, 5-9's is critical).
I'm located in Dallas, TX for any bids that might include
installation. We have a presense up to about 400 miles west of here.
