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

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

Building on the answer above, have a look at ESL labs -
who make such a<br>
relay that can bypass the PRI to the Asterisk server. As
well, have a<br>
look at HAAst (<a moz-do-not-send="true"
href="http://www.telium.ca" rel="noreferrer"
target="_blank">www.telium.ca</a>) which can monitor
Asterisk and then<br>
control the ESL relay to bypass Asterisk in case of
failure.<br>

P.S. My opinions do not necessarily reflect those of my
employer. As I<br>
am employed by Telium you can bet that me opinions are
biased!<br>

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.<br>
<br>
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).<br>
