[cisco-voip] Phone System Outages

[Todd Franklin]

Ed, I wouldn't think my internal calls need to go through the 2801.  CCM and
Unity hang off a 3560G (along with a 3560POE and the 2801).  So my
assumption has always been the call gets 'built' through the CCM, the
'route' is then set, and then CCM can drop out of the picture pretty much.
But I will need to confirm that.

Thanks.  I'm going to go dig through the Cisco site now for that document.
My 2801 is running 12.3(11)T9.
