Use the Serial Number to look up the MAC address on a phone

[speedie49]

When I order new Cisco Phones from our Vendor they ship me a list of the Serial Numbers.  Is there a way to use those serial numbers to look up the MAC address to put the phone into Call Manager to setup the extensions?

No, this piece of information are diferent. If you want take mac address, you can plug it on a switch port and check the mac address learned by this port. cdp is responsible for it.

Thanks in advance.
