[Asterisk-Users] Multiple X100Ps -- order?

They will keep the same configuration.  It's the magic tech faeries that
make it work as such. :)

Subject: [Asterisk-Users] Multiple X100Ps -- order?

After over a month (well, ok, no more than an hour a day :) of planning,
getting hardware, tinkering and testing, I'm about to my Ultimate Home
Phone System (tm) online.

Connectivity to the outside world is provided by:
A. 1 POTS phone line connected through an X100P ($11/month, needed to
carry DSL)
B. 1 Vonage ATA186 connected through an X100P (needed for the rate
center :( )
C. 3 Broadvoice DIDs connected via SIP
D. 1 sipgate.de DID connected via SIP
E. IAXTEL, FWD -- just because, not we really need these for incoming.

For incoming connections, the Vonage and Broadvoice DIDs are doing a
pseudo-hunt using Busy-Forward, which terminates in the POTS line.  For
outgoing connections, I'm using:

- IAXTel for 8xx numbers
- Broadvoice for statewide destinations
- Vonage for long distance calls
- POTS line for 911 calls

However, my concern is that Asterisk will keep its Zap channels straight
-- I already identified which of my X100P is assigned to which Zap
channel, but as I'm not too familiar with the PCI bus specs, I'm
concerned that this assignment may be random, and subject to change
after reboot.  Is that possible?  If the assignment changes, I'd
suddenly route all long-distance calls through my POTS line, which would
be considerably more expensive than Vonage.  And * would bark up Vonage
for a 911 call, which would be a "Bad Thing" if my wife called 911
because she or junior needed to do that.

So -- once I set up *'s ZAP channels, is there some PCI magic keeping
them in place, and/or assuring repeatable configuration?  If yes, I'd be
curious to know how it does it.  If No, does anyone have a test-call
script (upon reboot, use SIP to dial POTS or Vonage and see which ZAP
channel it's coming in on).

Thanks,
-- Jay
