[cisco-voip] *nix box for DHCP/TFTP

That's the biggest thing, update a phone via CCMadmin and then you have to 
manually update the TFTP server with that file.

The infoblox appliance supposedly has an agent that takes care of that for 
you.

One of my worries is updating the service parameter that rights these files 
for 7500 devices - I can't imagine how long that would take.

What I don't understand is why CCM doesn't have a parameter that says 
"location of external TFTP server" and allows you to put in an IP address. 
It could then update the files on that remote server via, um, let me guess, 
TFTP?????

It's a conspiracy I tell you.

Somebody out there is laughing to himself, "muhahahahahahaha, lelio will 
never get forwarding on his secondary lines"
