Configuring VG248 Ports Using Cisco CallManager


The VG248 connects to Cisco CallManager to provide access from the analog phones to Cisco CallManager or from Cisco IP Phones to an analog voice mail system. Each port on the VG248 corresponds to an analog device or voice mail port in your IP telephony network. To manage these devices and voice mail ports using Cisco CallManager you must add the VG248 to the Cisco CallManager database and configure the individual ports, which are managed as phones by Cisco CallManager.

These sections provide information about adding and configuring the VG248 and its ports to Cisco CallManager, but for detailed installation and configuration instructions about Cisco CallManager, refer to the documentation and online help included with it:

Configuring Voice Mail Ports

Adding the VG248 to Cisco CallManager

Cisco CallManager enables you to automatically register the VG248 and its ports or manually add them to the Cisco CallManager database. You can choose whichever method works best in your environment.

These sections provide the details about using auto-registration or manually adding the VG248 and its ports to Cisco CallManager:

Using Auto-Registration

Manually Adding the VG248 Cisco CallManager

Using Auto-Registration

You can choose to have the VG248 automatically added to Cisco CallManager using auto-registration. To do this, you must

Verify that auto-registration is enabled in Cisco CallManager. Refer to the documentation or online help included with the Cisco CallManager application for details.

If you are using the VG248 with analog phones, verify that the VG248 port enable policy is set to "auto." See the "Setting the Port Enable Policy" section for details.

If you are using the VG248 with analog voice mail systems, you should enable the voice mail ports to enable them to register with Cisco CallManager. See the "Enabling a Specific Port" section for details.

The procedures differ slightly depending on the version of Cisco CallManager you are using in your network. Be sure to refer to the applicable set of instructions.

Auto-Registering with Cisco CallManager 3.1

When the VG248 connects to Cisco CallManager 3.1 using auto-registration, each enabled port attempts to register with Cisco CallManager. Cisco CallManager first determines if the port has previously registered or verifies that the port can register using auto-registration. Then, Cisco CallManager adds the port to its database.

Phone Port

During auto-registration, the following fields are automatically populated for the VGC phone record for each port on the VG248:

MAC address—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.

The number is shifted two places to the left.

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

Description—The Cisco CallManager device name assigned to the VG248 (see the "Changing the Cisco CallManager Device Name" section) is entered in the Description field in the record for the emulated phone in Cisco CallManager. By default, the following sequence applies for the device description: VGC + the last 10 digits of the MAC address.

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 or voice mail port (see the "Configuring Analog Phone Ports" section or the "Configuring Voice Mail Ports" section).

After adding each port, make configuration changes as described in the "Configuring Analog Phone Ports" section or the "Configuring Voice Mail Ports" section.

Auto-Registering with Cisco CallManager 3.2 or 3.3

When the VG248 connects to Cisco CallManager 3.2 or 3.3 using auto-registration, each enabled port attempts to register with Cisco CallManager. Cisco CallManager first determines if the port has previously registered or verifies that the port can register using auto-registration.

Cisco CallManager then determines if the VG248 gateway to which the port is connected already exists in the Cisco CallManager database. If it does not, Cisco CallManager first creates the VG248 gateway and then registers the port.

Gateway Device

During auto-registration the following fields are automatically populated for the VG248 gateway record:

MAC address—Only the last 10 digits of the MAC address are populated.

For example, if the MAC address on the VG248 is
000039A44218

the MAC address registered for the VG248 gateway in Cisco CallManager is
0039A44218

Description—The prefix, VGCGW, is appended to the MAC address.

For example, if the MAC address on the VG248 is
000039A44218

the MAC address registered for the VG248 gateway in Cisco CallManager is
VGCGW0039A44218

Phone Port

During auto-registration, the following fields are automatically populated for the VGC phone record for each port on the VG248:

MAC address—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.

The number is shifted two places to the left.

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

Description—The Cisco CallManager device name assigned to the VG248 (see the "Changing the Cisco CallManager Device Name" section) is entered in the Description field in the record for the emulated phone in Cisco CallManager. By default, the following sequence applies for the device description: VGC + the last 10 digits of the MAC address.

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 or voice mail port (see the "Configuring Analog Phone Ports" section or the "Configuring Voice Mail Ports" section).

After adding each port, make configuration changes as described in the "Configuring Analog Phone Ports" section or the "Configuring Voice Mail Ports" section.

Manually Adding the VG248 Cisco CallManager

If you want to assign specific directory numbers to the ports on the VG248 without using auto-registration or make considerable modifications to them, particularly with voice mail integration, you must manually add each phone to the Cisco CallManager database. The procedures differ slightly depending on the version of Cisco CallManager you are using in your network. Be sure to refer to the applicable set of instructions.

Manually Registering with Cisco CallManager 3.1

Procedure

To add a VG248 port to Cisco CallManager, follow these steps:


Step 1 From Cisco CallManager, choose Devices > Add a New Device.

Step 2 Choose Cisco VGC Phone from the Phone type menu.

Step 3 Click Next and enter these fields:

MAC address—Each port must have a unique MAC address. Use the auto-registration formula (see the "Auto-Registering with Cisco CallManager 3.1" section) to calculate the MAC address for each port.

Description—Use the Cisco CallManager device name or other name for the Description for each port (see "Changing the Cisco CallManager Device Name" section). For ease of administration, use a similar name for ports configured on the same VG248.

Display—Consider adding a descriptive line to the Display field, such as "Analog phone" or "Voice Mail Port", particularly if you are using a mix of analog or voice mail ports on the VG248. Cisco CallManager does not distinguish between these two types of VGC phone types, and this description can help you quickly see which ports are used for analog devices and which are used for voice mail

Step 4 Configure each port as described in the "Configuring Analog Phone Ports" section or "Configuring Voice Mail Ports" section.


Manually Registering with Cisco CallManager 3.2 or 3.3

With Cisco CallManager 3.2 or 3.3, you add the VG248 first as a gateway and then you configure each of the ports individually as VGC phones.

Procedure

To add the VG248 to Cisco CallManager, follow these steps:


Step 1 From Cisco CallManager, choose Devices > Add a New Device.

Step 2 Choose Gateway from the device type menu.

Step 3 Choose Cisco VG248 Gateway from the Gateway type menu.

Step 4 Click Next and enter these fields:

MAC address—Enter the last 10 digits of the MAC address of the VG248 device. For details, see the "Auto-Registering with Cisco CallManager 3.2 or 3.3" section.

Description—Add a prefix or other identifier to the MAC address and enter it here. See the "Auto-Registering with Cisco CallManager 3.2 or 3.3" section for an example.

Step 5 Configure each port as described in the "Configuring Analog Phone Ports" section or "Configuring Voice Mail Ports" section.


Configuring Analog Phone Ports

Configuring the analog phone ports is very straight-forward. After the ports are added to the database (see the "Adding the VG248 to Cisco CallManager" section), you simply treat them as you would any other phone in your IP telephony network. For example, you need to add directory numbers, calling search space, and so on. Refer to the documentation and online help included with Cisco CallManager for details. To update these ports:

Cisco CallManager 3.1—From Cisco CallManager, choose Device > Phone to search for all registered VGC phones to update them.

Cisco CallManager 3.2 and 3.3—From Cisco CallManager, choose Device > Gateway to search for the VG248 gateway. Click on any of the ports from 01-48 to update them.


Note Using Cisco CallManager 3.2 or 3.3, do not enter any values in the Port Specific fields of the Phone Configuration window. These fields are not operational using the VG248 1.2(1) software. You must configure these settings locally on the VG248. See the "Configuring the Telephony Settings on the VG248" for details.


Configuring Voice Mail Ports

When using the VG248 to integrate SMDI, MCI, or Ericsson-compatible analog voice mail systems with Cisco CallManager, you must make changes to Cisco CallManager to support the VG248 and the end-user phones that will use this voice mail system.

These sections provide details about the necessary changes:

Calling Search Space—Choose a Calling Search space that enables this MWI port to access all phones on which it might need to set or clear MWI commands.

Directory number—Assign a unique directory number. If this port does not have a directory number, the VG248 cannot set or clear message waiting indicators.


Configuring Voice Mail Ports in Cisco CallManager

Using Cisco CallManager, you must add and configure each of the ports on the VG248 that are voice mail-enabled. To Cisco CallManager, each port is recognized and managed as a phone with the VGC phone type. So, if you have 10 ports on the VG248 that are voice mail-enabled, you need to add these 10 VGC phones (or ports) to Cisco CallManager.


Note If you plan to use the remaining 38 ports on the VG248 for analog devices, refer to the "Configuring Analog Phone Ports" section for instructions.


Cisco CallManager enables you to automatically register the ports from the VG248 or manually add them to the Cisco CallManager database (see the"Adding the VG248 to Cisco CallManager" section). After the ports are registered with Cisco CallManager, you can modify their settings.

Configuring the VG248

You must identify the number of voice mail ports locally on the VG248.
