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:
An H.323 Service prefix for outgoing video calls is defined as “0”.
The IP endpoint dials 067121212 to dial the UMTS number 67121212.
The gateway starts to call the UMTS handset and the “Connecting” picture and sound are activated.
Audio and video are transported through the gateway when the call is connected.
For more details on H.323 Services, please see ‘5.10 Services’.
