Hello,<br>
<br>
I've found a little documentation on voip-info and on the asterisk-<br>
users list, although I was hoping for an example of a tried-and-true<br>
failover setup between PRI and SIP.<br>
<br>
We are an outgoing call center that uses asterisk 1.4 connected to 2<br>
PRIs from the local telephone company in one group (g1) and a SIP<br>
trunk from <a href="http://bandwidth.com" target="_blank">bandwidth.com</a>. The PRIs are the primary outgoing service,<br>
however we have been experiencing some issues where one or both of<br>
them can fail randomly. We are working with the telephone company to<br>
have this resolved.<br>
<br>
In the meantime, we want to have a good failover solution where if<br>
both PRIs fail, asterisk will dial out through the SIP trunk. I've<br>
found solutions as simple as two Dial commands one after the other,<br>
and others where the failover Dial is in a jump to CONGESTION.<br>
Unfortunately we don't have a testing environment, so the solution<br>
really has to work.<br>
<br>
Does anyone else on the list have a PRI to VoIP failover setup that's<br>
worked for them in a high volume environment?<br>
<br>
Thanks!<br>
<br>
