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 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>
