Are you having a problem, or is it just the message that bothers you?

The error is often not relevant... How long does boot take with the network cable unplugged, and how many IP phones? A large system could take an hour or so boot, depending on platform, network, number of IP devices, etc

It's probably more of a curiosity than a problem, but if I was in your shoes I would be keen to solve the mystery.
 
Can you find anything in the logs showing it trying to resolve an IP address during bootup?
 
In the absence of this information, I would check:
 - the MCD IP addresses (controller, E2T and L2 switch addresses) - what are they?
 - MCD subnet mask and default GW - what are they?
 - MCD LAN port configuration - what VLAN? Tagged/untagged?
 - connected LAN switchport config - is there an extra VLAN here? What's the switchport config, exactly?
 - what DNS server(s) is/are configured on the controller?
 - scour the controller config and make a note of all hostnames and IP addresses that are configured (eg DNS, NTP, FTP, etc...).
 - Put a laptop on the same subnet as the controller and using the same DNS server as the controller resolve all hostnames to see what IP addresses are returned. Then check all the IP addresses to see if your IP network is properly designed or whether you have some mismatched subnet masks and/or overlaps.

At a guess, I would say your LAN has something funny in the way it is setup, eg you have two subnets on the same Layer2 segment and one of the devices your controller is trying to talk to has a smaller subnet mask than it should.
