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 support three different dial out services:
- “DiD” Direct outwards dialing of a 3G handset.
- “IVR” Dialing 3G terminals via selection menu.
- “Phonebook” Selecting entry from 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.
