TANDBERG Gateway

Technical Description of

with software version G2

4.1.3 Dial In Services

By enabling this feature, it is possible to make a direct mapping between ISDN numbers and

H323 aliases. This requires that the PRI lines connected to the TANDBERG Gateway are

configured with a range of numbers. This range of numbers should be large enough to associate

one ISDN number to each H.323 device that is intended to make use of the DID feature.

The H.323 aliases must be a portion of the ISDN number plus a prefix.

Example:

The TANDBERG Gateway is configured to use 4 digits of the ISDN Number, and 9 as the

H.323 prefix:

An endpoint dials the ISDN number 67117780

The TANDBERG Gateway transfers the call to the H.323 Alias 97780

This feature is used when one 'main' ISDN number is used for the TANDBERG Gateway. When

dialing into the TANDBERG Gateway on this number, the user will be greeted with a welcome

picture and sound. The user can then enter the H.323 Alias of the site they wish to call using

DTMF tones.

IVR should be used when one single ISDN number is to be used for the TANDBERG Gateway

and when the endpoints using H.323 should be independent of the ISDN number used for the

TANDBERG Gateway.

TCS-4 uses the same ISDN number as IVR. The user can add the H.323 alias to the ISDN

number separated by a * . The TANDBERG Gateway will automatically transfer the call to the

H.323 alias.

Example:

Endpoint dials 6711111*1234

Gateway will transfer the call to the H.323 alias 1234
