Updates to Cisco CallManager Compatibility
You configure the VG248 differently depending on the version of Cisco CallManager you are using in your network. Refer to these sections for tips on using the VG248 with your version of Cisco CallManager:
Using Cisco CallManager Version 3.1
The Cisco VG248 Analog Phone Gateway Software Configuration Guide provides the information needed to use the VG248 with Cisco CallManager 3.1. Refer to the "Documentation Roadmap" section for information on obtaining this document.
To use auto-registration with the VG248 and Cisco CallManager 3.1, you must use Cisco CallManager 3.1(3a), which is available at the following location on Cisco.com: http://www.cisco.com/cgi-bin/tablebuild.pl/callmgr-31.
Using Cisco CallManager Version 3.2
Cisco CallManager 3.2 includes some interface changes that require you to manage the VG248 slightly differently than with Cisco CallManager 3.1. These sections provide details about these changes:
Changes to the Cisco CallManager Interface
When using the VG248 with Cisco CallManager 3.2, you have access to new features, including:
•The addition of a VG248 gateway type
This allows you to add the device as a gateway to Cisco CallManager and configure each of the ports as VGC phone models. This consolidates each of the 48 analog or SMDI ports onto a single device. However, once you add the gateway and ports to Cisco CallManager, you still must configure these ports in the VG248 interface. See the "Adding the VG248 Gateway to Cisco CallManager" section for details.
•An additional port, port 00[VMI] appears on the VG248 Gateway Configuration window.
This port appears if you are using the VG248 to integrate analog or SMDI devices. However, the VG248 uses this port only when setting or clearing MWIs on phones using SMDI. See the "Configuring VG248 Analog Ports" section for details on configuring ports.
When using the VG248 with Cisco CallManager 3.2, these important caveats apply:
•You cannot use auto-registration to add a VG248 to Cisco CallManager 3.2.
You must add the VG248 to Cisco CallManager manually. See the "Adding the VG248 Gateway to Cisco CallManager" section for details.
•If you are upgrading to Cisco CallManager 3.2 from Cisco CallManager 3.1, and you already have a VG248 configured in the database, the information is retained.
During the upgrade process, Cisco CallManager automatically creates a new VG248 gateway device based on the port information you entered in Cisco CallManager 3.1
•On the VG248 gateway configuration page in Cisco CallManager, the Reset Device button does not work.
•When configuring the VG248 ports as VGC phone models, additional fields that are not used by the VG248 appear, including:
–Line text label
–MW lamp policy
You can ignore these fields; they are not used by the VG248.
•If you perform a search for the VG248 gateway type (from Device > Gateway in Cisco CallManager Administration) the results indicate "Device Not Found".
Although you cannot locate the device using the gateway search, you can search for the VGC phone model.
•After configuring one port (VGC phone) on the VG248, Cisco CallManager provides the option to "Configure all ports like Port 1".
If you use this option, Cisco CallManager automatically configures 49 ports, rather than 48. You can delete port 49; it is not functional.
Adding the VG248 Gateway to Cisco CallManager
With Cisco CallManager 3.2, you must manually add the VG248 as a gateway following this procedure:
Step 1 In Cisco CallManager, choose Devices > Add a New Device > Cisco VG248 Gateway.
Step 2 Enter this information for the gateway:
•MAC Address—Enter the last 10 digits of the Media Access Control (MAC) address for the VG248.
Only one MAC address exists for the Cisco VG248 Analog Phone Gateway, but Cisco CallManager requires unique MAC addresses for all devices. By entering only 10 digits of the MAC address, Cisco CallManager is able to use the MAC address for the gateway and append additional information to it to create the MAC addresses for the VGC phones. See the "Configuring VG248 Analog Ports" section for details.
•Description—Enter the purpose of the device, such as VG248 gateway.
Step 3 Click Insert.
Step 4 Choose 48_PORTS from the Installed Ports section.
Step 5 Click on a port to configure.
Step 6 Configure each port as described in the "Configuring VG248 Analog Ports" section.
Configuring VG248 Analog Ports
Each port on the VG248 corresponds to an analog or SMDI 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. For example, if you have 48 devices connected to the VG248, you must add and configure 48 ports to Cisco CallManager. Cisco CallManager recognizes 48 separate phones connected to it.
Note Ports 1-48 are available for use with analog devices or for SMDI connections. If you are using the VG248 with SMDI, port 00 is used to transmit and receive voice mail messages to Cisco CallManager. If you are using the VG248 for analog devices only, this port appears, but it is not functional.
Before You Begin
This procedure is identical in Cisco CallManager 3.1 and 3.2 and is also described in the Cisco VG248 Analog Phone Gateway Software Configuration Guide. It is included here for your convenience.
However, this procedure describes the process for adding analog ports to Cisco CallManager. If you are using the VG248 to integrate SMDI devices with Cisco CallManager, you must refer to the detailed procedures included in the software guide. See Chapter 5, "Integrating Cisco CallManager with Voice Mail Systems Using SMDI" in the Cisco VG248 Analog Phone Gateway Software Configuration Guide for details:
Step 1 Enter the appropriate fields, following these recommendations:
•The MAC address automatically appears based on the MAC address of the VG248, according to these guidelines:
–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.
•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."
Step 2 Click Insert.
Step 3 To add a directory number to this phone, click OK and enter the appropriate settings.
If you need assistance entering the directory number information, refer to the documentation and online help included with Cisco CallManager for details.
Fax Over IP Support
The VG248 supports fax pass-through and Cisco fax relay using the Skinny Client Control Protocol (SCCP). For detailed information about fax support on this and other Cisco voice gateways, refer to the Implementing Fax Over IP on Cisco Voice Gateways document available from Cisco.com at the following location:
