When the VG248 connects to Cisco CallManager through auto-registration, each
port connected to an analog device registers itself as a Cisco VGC phone.
Auto-registration automatically assigns phones a directory number. The directory
number assigned is the next one available in sequential order within the device
pool assigned to this phone type in Cisco CallManager. However, if you need to,
you can modify this directory number for each emulated phone (see the
"Configuring the VG248 Analog Ports" section on page
During auto-registration, the host name assigned to the VG248 is entered in the
Description field in the record for the emulated phone in Cisco CallManager. If
you do not enter a host name, the following sequence applies for the device
description: VGC + the last 10 digits of the MAC address.
Additionally, Cisco CallManager requires unique MAC addresses for all devices,
but all 48 ports on the VG248 share the same MAC address. Therefore,
auto-registration includes a process that converts the MAC addresses into this
format:
The first two digits of the MAC address are dropped.
