Chapter 5 Integrating Cisco CallManager with Voice Mail Systems Using SMDI
Configuring SMDI Settings on the VG248

Cisco VG248 Analog Phone Gateway Software Configuration Guide

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 SMDI 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.
Step 1
From the main menu, choose Configure.
Step 2
Choose SMDI.
Step 3
Choose First voice mail port number.
Step 4
Enter the voice mail pot index which corresponds to port 1 of the VG248.
Setting SMDI 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 either 7- or 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.
Step 1
From the main menu, choose Configure.
Step 2
Choose SMDI.
Step 3
Choose SMDI number length.
