I use the SG560 (http://www.snapgear.com/index.cfm?skey=1557) to do this. It handles two WAN connections (going to your ADSL modems). I set the routing policies so that VOIP goes on one link by default, and everything else on the other. If one link goes down, everything will be routed on the remaining link. (Unfortunately, it doesn't seem to revert to the default state after the downed link recovers, so I have to add some reboot-modems-after-recovery scripts in a cron job to make things recovery in an ideal way.) I think you can do the same with the Cisco RV016, which is cheaper, but the documentation is poor. - Mike -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
