TANDBERG 3G Gateway User Manual

3.3 Dial from IP

IP endpoints and MCUs can call out through the gateway by using one of the services defined on the gateway. The gateway supports three different dial out services:

-“DiD” Æ Direct Inward Dialing to a 3G handset.

-“IVR” Æ Dialing 3G terminals via a selection menu.

-“Phonebook” Æ Selecting an entry from a gateway phonebook.

Services

Service prefixes are used for IP endpoints to access UMTS Handsets. Up to twenty services/prefixes can be defined, but we recommend using one single prefix for simplicity.

Example:

ƒAn H.323 Service prefix for outgoing video calls is defined as “0”.

ƒThe IP endpoint dials 067121212 to dial the UMTS number 67121212.

ƒThe gateway starts to call the UMTS handset and the “Connecting” picture and sound are activated.

ƒAudio and video are transported through the gateway when the call is connected.

For more details on H.323 Services, please see ‘5.10 Services’.
