Configuring DNIS
DNIS (Dialed Number Identification Service) is a telephone service that identifies for the the receiver of the
call the number that the caller dialed. DNIS works by passing the touch-tone digits (dual-tone multi-frequency
of MF digits) to the destination where a special facility can read and display them or make them available for
use by the terminating device.
The RAS uses its ability to capture DNIS information to provide the customer the ability to set up parameters for
their dial-in clients based on the phone number that has been dialed or which physical WAN port they have dialed
into. If none of the specified conditions are met then the default conditions of the RAS will be applied to the user.
In its current implementation the following parameters can be configured based on DNIS:
• Authentication: can select traditional authentication or no validation
• IP Address Pool
• Data over voice bearer services
Setting up IP address pools by configuring DNIS Ip Pools
Note
This section is optional. If you are not going to set up IP address pools, refer
to section
“Setting up a DNIS user profile”.
If IP address pools are to be assigned based on DNIS or WAN port, configure your DNIS Ip Pools (see
figure 35 on page 86) as follows:
1. Enter an ID number to identify the IP address pool
2. Enter the IP address range.
3. Click on the
Submit Query
button.
Setting up a DNIS user profile
Set up a DNIS user profile (see figure 33 on page 81) to be applied based on DNIS or WAN port as follows:
1. Enter an ID number to identify the specific DNIS profile.
2. Enter the ID for the IP address pool if you wish to apply a specific set of IP addresses to these users. Use 0
if you wish the users to use the default IP address pool or a static IP address from RADIUS.
3. Set the authentication type.
4. Enable data over voice bearer services if desired. This allows either 64k or 56k ISDN calls.
5. If you wish to redirect the users to a remote host or service on a remote host then enter the remote host’s IP
address and port the application is listening at. For example, telnet listens on port 23.
6. Click on the
Submit Query
button.
Setting up a DNIS group
Set up a DNIS group (see figure 31 on page 77) as follows:
1. Enter an ID number to identify the specific DNIS profile.
