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. Using fewer than 48 ports for SMDI
means that the remaining ports can be used for connecting analog phones,
modems, or fax machines.
If you use fewer than 48 ports for SMDI, you must ensure that the SMDI 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 analog devices.
Step 1
From the main menu, choose Configure.
Step 2
Choose SMDI.
Step 3
Choose Number of SMDI ports.
Step 4
Enter the number of SMDI 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.
