Responding to Matt Riddell, M Shokuie, A J Stiles, and Telium Support
(all below)
Thanks for the suggestions, but a separate gateway is a problem in the
design as the configuration is basically:
Carrier --- PRI --- Asterisk (with failover) ---- Legacy PBX
|
- SIP / IAX2 -- our service or remote office
As this is already acting as a gateway adding another box to the mix
seems a bit over kill (unless I can embed it and the asterisk PBX into
a 2 U pizza box). But since most gateways are designed to be used for
fail over servers / PBXs not lines I am not sure that this would
benefit us.
So far I have found 1 company that seems to have a gateway card and
that is the beroNet PCI / PCIe Gateway Cards which they say has the
card level failover. I will update the list should this meet the use case.
Eric

Hi there,
Using Sangoma Vega400 gateway you'll have what is called
resilliency which
is exactly what you are looking for.
Regards.

Use a 4-pole change-over relay to switch the PRI connection either
to the
Asterisk box if it gets some sort of "heartbeat" signal from the
computer
(say, toggling one of the lines of a printer port, if the
motherboard still
has one), or the old PABX?
You might have to do some mean, down and dirty low-level
programming, to embed
your heartbeat-generating code in Asterisk's idle loop; but the
Source Code is
out there, if you fancy the challenge .....

Building on the answer above, have a look at ESL labs - who make
such a
relay that can bypass the PRI to the Asterisk server. As well, have a
look at HAAst (www.telium.ca <http://www.telium.ca>) which can
monitor Asterisk and then
control the ESL relay to bypass Asterisk in case of failure.

P.S. My opinions do not necessarily reflect those of my employer. As I
am employed by Telium you can bet that me opinions are biased!
If you place an ESL PRI A/B switch on either side of the Asterisk server
you can easily bypass the Asterisk server, or place it inline with the
PRI link.
You can also chose to TAP the lines as noted above, but you have to
ensure that both PRI cards don't go live at once...(if I understand that
product correctly).
