[cisco-voip] VoIP Failover Path

[Alex]

My memory can be rusty but I think you can do think using link-endpoint addresses as "session targets", also look into "PSTN fallback" for failover on bad quality.

  All-

  We have two Cisco2801 routers that can connect to each other serial to serial, or Ethernet to Ethernet:

   

    /--S0--{path1}--S0--\

  GW1                   GW2

    \--E0--{path2}--E0--/  

   

  Currently PATH1 is our default path.  How can we setup PATH2 for a backup path for VoIP dialpeers?  I've investigated the preference value, but with the preference, what triggers the failover?  

   

  Will/Can active Calls be passed between PATH1 and PATH2 without dropping if PATH1 goes down?  

   

  If call quality on PATH1 is bad, will PATH2 be used, will/can active calls be moved??

   

  Thanks!

  ~Todd
