How can I get the serial numbers of the IP phones?

[parkynk]

Is there any way to get the serial numbers of of the phones from the 3300?
I need a method to validate which phones are allocated to which department.

Thanks

  I'd consider using the MAC addresses.  They are available in the controller and are all unique.  Also, they are on a sticker on the phone for physical checks.  I don't think that serial numbers are in the controller....

If your luckily enough to have cisco POE routers your can issue the "show cdp neighbor" command and it will give you a list of mac address (after the SEP)
eg:
Level-10-SW1#sh cdp nei
Capability Codes: R - Router, T - Trans Bridge, B - Source Route Bridge
                  S - Switch, H - Host, I - IGMP, r - Repeater, P - Phone,
                  D - Remote, C - CVTA, M - Two-port Mac Relay

Device ID        Local Intrfce     Holdtme    Capability  Platform  Port ID
SEP08000F285315  Fas 1/0/24        127              H P   Mitel 521 Port 1
SEP08000F268A7C  Fas 1/0/29        145              H P   Mitel 521 Port 1
SEP08000F258EE5  Fas 1/0/39        148              H P   Mitel 534 Port 1
SEP08000F26EB18  Fas 1/0/13        152              H P   Mitel 521 Port 1
SEP08000F281375  Fas 1/0/2         136              H P   Mitel 521 Port 1
SEP08000F25BA96  Fas 1/0/15        175              H P   Mitel 534 Port 1
SEP08000F274AE9  Fas 1/0/16        165              H P   Mitel 521 Port 1

Or to find the DN's and model number allocated to the phone's connected to the switch do
Level-10-SW1#sh cdp nei det | in DN
