[cisco-voip] VoIP Failover Path

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
