Dialling Rules - TANDBERG MPS User Manual

TANDBERG MPS User Manual

.1 Dialling Rules

General
In order to enable the Gateway functionality in the MPS, the Gateway SW option must be set. The option key is set in
the web interface in the [System configuration] tab under [Upgrade]. An option key for the Gateway can be obtained
through the regular TANDBERG channels. The option key states how many Gateway sessions, the MPS is able to run
in parallel. A Gateway session requires 2 ports (one for the source side and one for the destination side), thus making
80 the maximum number of Gateway sessions for the MPS 800.
Once the correct option key for the Gateway is entered (and the system restarted), the web interface will include a
Gateway overview page, see Figure 3‑11 G��ew�� ���� �verview . An extra tab for Gateway configuration will also be
added to the web interface.

Dialling Rules
The dialling rules must be set in order for the MPS to handle different types of Gateway calls. The different Gateway
call types supported by the MPS are DID, IVR and IVR-TCS4.
DID
Direct Inward Dialling (DID) will provide you with a direct dial-in numbers for your endpoints.
I.e. it will do a direct mapping between your ISDN number and the H.323 Alias: If you have assigned a range of ISDN
numbers to your ISDN PRI line, each ISDN number will map to a single IP endpoint.
Note: We recommend that if more than one PRI line is used all PRI lines should have a common number range (use
trunk groups).
Example:
•
A DID dialling rule exists that maps the PRI number range from 67124000 to 67124050 to the H.323 Alias
range 94000 - 94050.
•
To call an IP endpoint with H.323 Alias 94020 from ISDN, dial the ISDN number 67124020.
