</div>My solution was to create a rsync script to copy the configuration of<br>
the primary server to the standby (every 15m).<br>

<br>
</div>Yes, there are E1 switches. I use this one:<br>
<a href="http://www.oriontelecom.com/pro_switch/e1_switch/e1_failover_switch.html" target="_blank">http://www.oriontelecom.com/pro_switch/e1_switch/e1_failover_switch.html</a><br>
I disabled the automatic failover detection though, a script that is run<br>
when the standby becomes active switches the circuits from A to B or the<br>
otherway around.<br>
<br>
An other way is to use an external E1 to SIP gateway. Cons are that they<br>
are more expensive then Digium hardware and you still need more than 1<br>
if you want to avoid this being a single point of failure. But they can<br>
be more flexible in some setups (multiple active asterisk machines<br>
connecting simulataniously)<br>
