The two-digit port number is added to the right.
For example, if the MAC address on the VG248 is
000039A44218
the MAC address registered for port 12 in Cisco CallManager is
0039A4421812
After adding each port, make configuration changes as described in the
“Configuring the VG248 Analog Ports” section on page 4-3
.
Manually Adding the VG248
If you want to assign specific directory numbers to the emulated IP phones on the
VG248 without using auto-registration, you must manually add each phone to the
Cisco CallManager database. Keep in mind several important facts:
•
To add a VG248 port to Cisco CallManager,
a.
From Cisco CallManager, choose Devices > Add a New Device.
b.
Choose Cisco VGC Phone from the Phone type menu.
c.
Click Next.
•
Each port must have a unique MAC address. Use the auto-registration
formula (see page 4-2) to calculate the MAC address for each port.
•
Use the host name or other name for the Description for each port. For ease
of administration, use a similar name for ports configured on the same
VG248.
•
Consider adding a descriptive line to the Display field, such as “Analog
phone.”
•
Configure each port as described in the
“Configuring the VG248 Analog
Ports” section on page 4-3
.
Configuring the VG248 Analog Ports
Each port on the VG248 corresponds to an analog device in your IP telephony
network. To manage these devices using Cisco CallManager you must add each
port to the Cisco CallManager database. To Cisco CallManager, each port is
recognized and handled as a phone.
