C H A P T E R Overview The Cisco VG248 Analog Phone Gateway (VG248) enables you to integrate analog telephones, modems, and fax machines with the Cisco CallManager IP telephony system. You can also integrate legacy voice mail and PBX systems with Cisco CallManager using Simplified Message Desk Interface (SMDI).
Cisco IP telephony network (see Figure 1-1). The Cisco VG248 offers 48 fully-featured analog phone lines to be used as extensions to the Cisco CallManager system in a compact 19-inch rack-mount chassis. Figure 1-1 VG248 Integrated in the Cisco IP Telephony Network...

Cisco CDP MIB Cisco Discovery Protocol (CDP) is a method that Cisco devices use to advertise their presence and to discover information about other nearby devices. The VG248 supports CDP and implements this MIB. You can enable or disable CDP on the VG248.
Page 29
This MIB allows detailed information to be retrieved for all memory pools present within a Cisco device. The VG248 implements this MIB, but because all dynamic memory management uses a single heap, the resulting table has one row, which is returned as “Processor”.

VG248. Enabling caller ID determines how the VG248 handles any caller ID instructions received from Cisco CallManager. If you are not using caller ID on Cisco CallManager, then the VG248 does not receive any caller information to pass on to the analog ports, regardless how you set the VG248.
Keep in mind that the VG248 only sends this information to the phones if it is received from Cisco CallManager. If Cisco CallManager is not integrated with your voice mail system, it does not send this information to the VG248.
Use the arrow keys to select the port to configure and press Enter. Step 4 Choose Output gain. Step 5 Step 6 Choose from the available options (ranging from -14dB through 0db) Cisco VG248 Analog Phone Gateway Software Configuration Guide OL-1209-02 3-13...
For example, if the base value is -3dB, you might choose +1dB as the delta value. Therefore, the actual gain value for that port is -2dB overall. Cisco VG248 Analog Phone Gateway Software Configuration Guide 3-14 OL-1209-02...
Configuring Analog Phones Using Cisco CallManager The VG248 connects to Cisco CallManager to provide access from the analog phones to Cisco CallManager. To configure the analog phones using Cisco CallManager, you actually configure the ports on the VG248. The changes you make to a specific port (such as disabling call waiting or assigning speed dials) apply directly to the analog device connected to that port.
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”...
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.

SMDI-based voice mail system. Before You Begin You should modify these settings on any Cisco IP Phones and on any analog phones connected to the VG248 that require access to this voice mail system.
To properly prepare the VG248 to support SMDI, you must modify some local configuration settings. Some of these SMDI settings must match settings on the voice mail system or Cisco CallManager. Therefore, you must be familiar with the configuration settings on those systems as well.
The pilot directory number configured on the VG248 must match the VoiceMail service parameter configured in Cisco CallManager, which is available by choosing Service > Service Parameters in Cisco CallManager. This enables the VG248 to distinguish between calls made to retrieve a user’s voice mail from calls made to leave a voice mail for another user.
Chapter 5 Integrating Cisco CallManager with Voice Mail Systems Using SMDI Configuring SMDI Settings on the VG248 Assigning Number of SMDI Ports By default, none of the ports on the VG248 are configured to send SMDI information about calls made to those ports. To enable SMDI, you must assign the number of SMDI ports a value from 1 to 48.
You can also set the number length to <unpadded>, which indicates that the voice mail box numbers are always passed unmodified between Cisco CallManager and the analog voice mail system. From the main menu, choose Configure.
Chapter 5 Integrating Cisco CallManager with Voice Mail Systems Using SMDI Configuring SMDI Settings on the VG248 Choose one of the following: Step 4 • • <unpadded> • Allowing SMDI Number to be Truncated If SMDI extension numbers are longer than the traditional 7 or 10 digits, the VG248 can either pass on the entire number or truncate the extension number to the length you defined in the SMDI number length.
Chapter 5 Integrating Cisco CallManager with Voice Mail Systems Using SMDI Configuring SMDI Settings on the VG248 However, the SMDI number format allows other digits to be used. For example, with a SMDI number format of 1234567, the extension number 8989 would become 1238989.
