The 3G Gateway is equipped with a number
of persistent default services, i.e. services
stored in the on-board non-volatile memory.
Therefore, these services will always
be available after a system restart. The
following persistent default services can be
distinguished:

Direct Inwards Dialing (DID)

•

– Defines a

one-on-one relation between an inbound
and an outbound number.

Dial Extension (IVR)

•

– Also known as

Interactive Voice/Video Response (IVR),
defines a relation between an inbound
number and an interactive service, i.e. a
menu, via which an outbound service can
be connected to. The outbound service
can be an audio or video service or an
externally connected endpoint.

TMS Corporate Directory

•

(phone book) – A

connection with the installed TANDBERG
Management System (TMS) phone book
is set up. Via the phone book menu an
outbound call to another endpoint, e.g. a
3G Mobile, H.323 or SIP endpoint, can be
set up.

When dialing number 67890000 this will match without leaving a
remainder. The H.323 number that will be connected to will be: 51234
(construction: prefix). When dialing number 67894321 there will be no
match. When dialing number 678900009876 one is also connected to
the same H.323 endpoint, since there is a match on 67890000 and the
remainder, i.e. 9876, is discarded. Note that

Example

A 3G handset user calls a Dial Extension service number.

The 3G Gateway activates the

Welcome

screen and sound.

The 3G Gateway, when set in the dial plan, shows the DTMF Information screen.

The 3G handset user enters the extension (H.324m, H.323 or SIP alias) followed by the

(pound-sign) to indicate end of number.

The 3G Gateway starts to call the endpoint and the

Connecting

picture and sound are activated.

When the call is connected audio and video are transmitted through the 3G Gateway.
