Configuring Voice Mail Settings


To properly prepare the VG248 to support analog voice mail systems that use implement SMDI, MCI, or Ericsson voice mail protocols, you must modify some local configuration settings. Some of these 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.

These sections provide details about the required configuration options:

Connecting the Voice Mail Links to the VG248

The voice mail protocols are RS-232-based serial protocols, and the VG248 has two serial ports for supporting voice mail connections, the Async 1 and Async 2 ports (see Figure 4-1).

Both serial ports operate at a default rate and format of 9600 baud, no parity, 8 data bits, one stop bit, and no flow control. However, you can change these settings (see the "Modifying Serial Settings for Async Ports" section for details). Use a standard RJ-45-to-RJ-45 rollover serial cable (up to 50 feet in length) and either an RJ-45-to-DB-9 adapter or an RH-45-to-DP25 adapter to connect the VG248 to other voice mail devices using these ports:

Async 1—the primary serial port used for connecting to the voice mail system (any configuration) or voice mail source (chained or multiplexing configuration). If you are using a single VG248 device, connect the voice mail system to the Async 1 port on the VG248. With multiple VG248 devices, use the Async 1 port to connect to the previous VG248 device's Async 2 port.

Async 2—used for connecting multiple VG248 devices together. If there are multiple VG248 devices in use, connect the Async 2 port of the first VG248 device (which is connected directly to the voice mail system via the Async 1 port) to the next VG248 device's Async 1 port. Continue to connect all the VG248 devices in the chain similarly. If you are connecting a legacy PBX system to the voice mail chain, connect the Async 2 port of the last chained VG248 device to the voice mail port of the legacy PBX.

Configuring Universal Voice Mail Settings

The VG248 supports several different analog voice mail protocols, including SMDI, MCI, and Ericsson. Although each of these protocols have some settings that are specific to them, many settings on the VG248 apply to all of these protocols.

These sections describe the voice mail settings on the VG248 that apply to all of the supported voice mail protocols:

Choosing a Voice Mail Protocol

You can integrate analog voice mail systems that are compatible with either SMDI, MCI, or Ericsson voice mail protocols.

Procedure

To choose the protocol used by your voice mail system, follow these steps:


Step 1 From the main menu, choose Configure.

Step 2 Choose Voice mail.

Step 3 Choose Voice mail protocol.

Step 4 Choose one of the following options:

SMDI

MCI

Ericsson


Identifying the Pilot Directory Number

The pilot directory number corresponds to the number users dial on their phones to access voice mail. 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.

The pilot directory number configured on the VG248 must match the value configured in Cisco CallManager. For information specific to your version of Cisco CallManager, see the "Configuring the Voice Mail Hunt Group Using Cisco CallManager 3.3" section on page 5-7 or the "Configuring the Voice Mail Hunt Group Using Cisco CallManager 4.0" section on page 5-19.

Procedure

To identify the pilot directory number, follow these steps:


Step 1 From the main menu, choose Configure.

Step 2 Choose Voice mail.

Step 3 Choose Pilot directory number.

Step 4 Enter the number, which corresponds to the setting in Cisco CallManager.


Assigning Number of Voice Mail Ports

By default, none of the ports on the VG248 are configured to send voice mail information about calls made to those ports. To enable the voice mail protocols, you must assign the number of voice mail ports a value from 1 to 48. Using fewer than 48 ports for voice mail means that the remaining ports can be used for connecting analog phones, modems, or fax machines.

If you use fewer than 48 ports for voice mail, you must ensure that the voice mail ports are consecutive ports beginning with port 1. For example, if this value is set to "10", VG248 ports 1 through 10 should be connected to the voice mail system and ports 11 to 48 are available for other analog devices.

Procedure

To assign the number of voice mail ports, follow these steps:


Step 1 From the main menu, choose Configure.

Step 2 Choose Voice mail.

Step 3 Choose Number of voice mail ports.

Step 4 Enter the number of voice mail ports.

The default setting is 0.


Identifying the First Voice Mail Port Number

With a single VG248 connected to a voice mail system (such as in the basic configuration), port 1 on the VG248 should be connected to port 1 of the voice mail system, and similarly for the other VG248 ports.

However, with multiple VG248 devices connected to a single voice mail system (such as in the chained configuration) this simple mapping is possible only on the first VG248. On the other VG248 devices, port 1 must connect to higher voice mail port numbers.

Using this setting, you can identify the first port used on the voice mail system. This value should correspond to the port number on the voice mail system to which port 1 is connected. In all cases, connections from a single VG248 must use consecutive, successive ports of the voice mail system.

For example, if two VG248 devices are connected to a 96 port voice mail system, one VG248 connects to ports 1-48, and the other connects to ports 49-96. On the first VG248 device, set the First voice mail port number to 1 (the default value) and set the value to 49 on the second VG248.

As another example, if 80 voice mail ports were in use and two VG248 devices were each providing 40 ports, the Number of voice mail ports on each VG248 would be set to 40, and the First voice port number would be set to 1 on the first VG248 and 41 on the second VG248.

Procedure

Follow these steps to change the first voice mail port number:


Step 1 From the main menu, choose Configure.

Step 2 Choose Voice mail.

Step 3 Choose First voice mail port number.

Step 4 Enter the voice mail port index which corresponds to port 1 of the VG248.


Setting the Number Format

In some instances, the VG248 must extend extension numbers before passing them to the voice mail system. For example, if the minimum length is set to more digits than are present in the Cisco CallManager voice mail box numbers, the VG248 adds zeroes to the left of the number. For example, if the Number length is set to seven digits. the extension number 1234 becomes 0001234

Number format allows other digits to be used. For example, with a Number format of 1234567, the extension number 8989 would become 1238989. Zeroes are used for any additional required digits. For example, with SMDI, if Number length was 10, the final extension number would be 0001238989. If the Number length is set to <unpadded>, this setting has no effect.

Procedure

Follow these steps to modify the number format:


Step 1 From the main menu, choose Configure.

Step 2 Choose Voice mail.

Step 3 Choose Number format.

Step 4 Enter the required number format.


Forwarding MWIs to Cisco CallManager

You can specify whether the VG248 sends MWI commands it receives from the voice mail system to Cisco CallManager.

Before You Begin

Follow these guidelines for enabling this setting based on your configuration:

Basic—Enable this on the VG248 system.

Chained—Enable this on only one of the VG248s in a chain, and for simplicity, set it on the one directly connected to the voice mail system.

Multiplexing—Enable this on one VG248 connected to each Cisco CallManager cluster.

Procedure

To forward MWIs to Cisco CallManager, follow these steps:


Step 1 From the main menu, choose Configure.

Step 2 Choose Voice mail.

Step 3 Choose Forward MWIs to CallManager.

Step 4 Choose one of the following:

yes

no


Forwarding MWIs to Async 2

You can specify whether the VG248 forwards MWI commands received from the voice mail system to the next device in the voice mail chain.

Before You Begin

Follow these guidelines for enabling this setting based on your configuration:

Basic—Do not enable this setting.

Chained—Enable this setting on all VG248 devices except the last device in the chain on which you have set Forward MWIs to CallManager to yes.

Multiplexed—Enable this setting on all VG248 devices if you are connecting to a legacy PBX system. Otherwise, follow the guidelines for the chained configuration.

Procedure

To forward MWIs to Async 2, follow these steps:


Step 1 From the main menu, choose Configure.

Step 2 Choose Voice mail.

Step 3 Choose Forward MWIs to Async 2.

Step 4 Choose one of the following:

yes

no


Identifying the Directory Number for Setting MWI on Cisco CallManager

If you have enabled the VG248 to forward MWI commands from the voice mail system to Cisco CallManager, you must identify the directory number used to set MWI commands.

These values must match the MWI settings configured in Cisco CallManager. For information specific to your version of Cisco CallManager, see the "Configuring the MWI Port Using Cisco CallManager 3.3" section on page 5-13 or the "Configuring the MWI Port Using Cisco CallManager 4.0" section on page 5-26.

Procedure

To identify the directory number used to set MWI commands, follow these steps:


Step 1 From the main menu, choose Configure.

Step 2 Choose Voice mail.

Step 3 Choose CallManager MWI on DN.

Step 4 Enter the value that matches the parameter in Cisco CallManager.


Identifying the Directory Number for Clearing MWI on Cisco CallManager

If you have enabled the VG248 to forward MWI commands from the voice mail system to Cisco CallManager, you must identify the directory number used to clear MWI commands.

These values must match the MWI settings configured in Cisco CallManager. For information specific to your version of Cisco CallManager, see the "Configuring the MWI Port Using Cisco CallManager 3.3" section on page 5-13 and the "Configuring the MWI Port Using Cisco CallManager 4.0" section on page 5-26.

Procedure

To identify the directory number used to clear MWI commands, follow these steps:


Step 1 From the main menu, choose Configure.

Step 2 Choose Voice mail.

Step 3 Choose CallManager MWI off DN.

Step 4 Enter the value that matches the parameter in Cisco CallManager.


Modifying Serial Settings for Async Ports

The VG248 uses the Async 1 and Async 2 serial ports to transport voice mail protocols.

You can modify the settings on these ports to synchronize with those required by your voice mail system.


Note The console port, used to access the VG248 menu interface through a serial connection, remains fixed at: 9600 baud, 8 data bits, no parity and 1 stop bit.


Async port speed

This parameter defines the baud rate used for the Async 1 and Async 2 serial connections used to connect VG248 devices to an analog voice mail system or to a legacy PBX. The speed of the Async 1 and Async 2 must be the same, and this speed must match the baud rate of the analog voice mail system's port. If you have chained multiple VG248 devices together, ensure that each device is set to the same port speed.

Async 1 or 2 Data Bits

You can set the number of data bits being used for the serial connection of the Async 1 or Async 2 port to be 8 (the default value) or 7.

Set this value to match the corresponding setting of the device to which the Async port is connected.

Async 1—setting should match the setting on the voice mail port of the analog voice mail system or the Async 2 port of the next VG248 device in the chain.

Async 2—setting should match the legacy PBX or the Async 1 of another VG248 device.

Async 1 or 2 Parity

You can set the parity on the Async ports to: none (the default setting), even or odd.

Async 1—setting should match the setting on the voice mail port of the analog voice mail system or the Async 2 port of the next VG248 device in the chain.

Async 2—setting should match the legacy PBX or the Async 1 of another VG248 device.

Async 1 or 2 Stop Bits

You can set the number of stop bits being used for the serial connection of the Async 1 or 2 port to be set to either 1 (the default value) or 2.

Async 1—setting should match the setting on the voice mail port of the analog voice mail system or the Async 2 port of the next VG248 device in the chain.

Async 2—setting should match the legacy PBX or the Async 1 of another VG248 device.

Procedure

Follow these steps to modify the async port settings:


Step 1 From the main menu, choose Configure.

Step 2 Choose Voice mail.

Step 3 Choose Async port serial settings

Step 4 Choose one of the following and choose the appropriate setting:

Async port speed

Async 1 data bits

Async 1 parity

Async 1 stop bits

Async 2 data bits

Async 2 parity

Async 2 stop bits


Configuring SMDI Settings

These sections provide information about configuring settings on the VG248 to support analog voice mail systems using SMDI:

Assigning the Message Desk Number

Setting Voice Mail Number Length

Allowing Voice Mail Number to be Truncated

Defining Directory Numbers With Leading Zeros

Forwarding INV Responses to Async 1

Entering a Keep Alive Number

Configuring Disconnect Notification

Assigning the Message Desk Number

Typically, a voice mail system is configured with a single Message Desk Number (normally 1), and incoming SMDI messages are required to use this value for proper operation. You need to set the message desk number on the VG248 to match the value used by the voice mail system.

Before You Begin

If you are using the chained configuration all devices in the SMDI chain should use the same message desk number.

Procedure

To choose the message desk number, follow these steps:


Step 1 From the main menu, choose Configure.

Step 2 Choose Voice mail.

Step 3 Choose SMDI settings.

Step 4 Choose Message desk number.

Step 5 Enter the message desk value used by your voice mail system.


Setting Voice Mail Number Length

Traditional SMDI includes caller and called party information as 7-digit numbers. If the number is shorter than 7 digits, extra digits (typically zeros) are added to the left. For example, the extension number "12345" becomes "0012345" when sent via SMDI. However, because 7 digits are not enough for external caller ID, an extended SMDI format is available that uses 10-digit numbers.

Most voice mail systems are flexible, supporting either SMDI format. However, some older systems insist on receiving exactly seven digits. Check the voice mail system's documentation to determine which setting is most appropriate.

You can set the VG248 to output using any value from 2-10 digit numbers. It should match the value required by your voice mail system. 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.

Procedure

Follow these steps to change the voice mail number length:


Step 1 From the main menu, choose Configure.

Step 2 Choose Voice mail.

Step 3 Choose SMDI settings.

Step 4 Choose Voice mail number length.

Step 5 Choose one of the available options, ranging from 2-10 or <unpadded>.


Allowing Voice Mail Number to be Truncated

If SMDI extension numbers are longer than the specified Voice mail number length, the VG248 can either pass on the entire number or truncate the extension number to the length you defined.

Most voice mail systems can accept longer numbers, but some systems insist on an exact number of digits. Check which format your system supports before selecting this option. If the Voice mail number length is set to <unpadded>, this setting has no effect.

Procedure

Follow these steps to allow the voice mail number to be truncated:


Step 1 From the main menu, choose Configure.

Step 2 Choose Voice mail.

Step 3 Choose SMDI settings.

Step 4 Choose Truncate number if too long.

Step 5 Choose one of the following:

yes—to restrict the number length to 2 or 10 digits

no—to pass on the entire number


Defining Directory Numbers With Leading Zeros

If you have enabled the VG248 to forward MWI commands from the voice mail system to Cisco CallManager and the directory numbers contain leading zeros, you must define the length of the directory number. Otherwise, the VG248 will truncate the leading zero.

You can set the directory number to any length from 2-10 digit numbers. For example, for extension 0351, set the directory number length to 4.

By default, the length of directory numbers is not specified.

Procedure

To define the length of the directory number, perform these steps:


Step 1 From the main menu, choose Configure.

Step 2 Choose Voice mail.

Step 3 Choose SMDI settings.

Step 4 Choose DN length.

Step 5 Choose a number from 2 through 10 to define the directory number to that length.


Forwarding INV Responses to Async 1

Some PBX systems generate an INV response to MWI commands from the voice mail system if an error occurs. These INV responses are received on the Async 2 port of a VG248 attached to the PBX.

The VG248 cannot distinguish which extension numbers are connected to the legacy PBX and which are connected to Cisco CallManager. Therefore, MWI commands are sent to both systems. If the VG248 is connected to a legacy PBX and Cisco CallManager (such as in the multiplexing configuration), the PBX is likely to generate these error responses to commands it receives from the VG248.

Procedure

Follow these steps to forward INV responses to Async 1:


Step 1 From the main menu, choose Configure.

Step 2 Choose Voice mail.

Step 3 Choose SMDI settings.

Step 4 Choose Forward INV responses to Async 1.

Step 5 Choose one of the following:

yes—errors generated by the PBX are sent to the voice mail system.

no—default setting


Entering a Keep Alive Number

Some voice mail systems use a Keep alive number to determine whether or not the SMDI connection is active. The voice mail system sends out a test MWI operation for this voice mail box number and expects to receive a negative response from the attached VG248.

You must configure the VG248 with this keep alive number so it distinguishes the MWI commands on this number from those on a real extension number.

By default, this value is set to 5551212, which is a number commonly used for this purpose by analog voice mail systems.

Procedure

To enter a keep alive number, follow these steps:


Step 1 From the main menu, choose Configure.

Step 2 Choose Voice mail.

Step 3 Choose SMDI settings.

Step 4 Choose Keep alive number.

Step 5 Enter the extension number.


Configuring Disconnect Notification

When a remote party hangs up, the voice mail system should detect this so it can hang up also, freeing the port for use by another caller. If this parameter is set to yes, the VG248 sends an additional SMDI message to the voice mail system when a call into it has finished. This message is not part of the SMDI standard. By default, this option is set to no.

Procedure

To configure the disconnect notification, follow these steps:


Step 1 From the main menu, choose Configure.

Step 2 Choose Voice mail.

Step 3 Choose SMDI settings.

Step 4 Choose Disconnect notification.

Step 5 Choose one of the following:

yes

no
