It seems the ITG card monitors the quality of the IP network before making a call. If quality is poor, it is possible to select an alternate route.
How is the ITG card checking the QOS ?



 
I think it looks at the delay of the packets. Or does somethink like a ping...

If Bill Gates had a nickel for every time Windows crashed... Oh wait, he does...
 
This is from an ITG log file..you can see the packet speeds in ms,

Tx: 0.00 -166ms Excellent Rx: 0.00 93ms Excellent
Codec: G729B G729AB
Tx: 0.00 -166ms Excellent Rx: 0.00 93ms Excellent

And this is the log file during an outage

Tx: 0.00 500093ms Poor Rx: 100.00 0ms Poor
Codec: G723_5 G723_6
Tx: 0.00 500093ms Poor Rx: 100.00 0ms Poor
Codec: G729 G729A
