TANDBERG 3G Gateway User Manual 3.2 Dial from UMTS The gateway supports tree different UMTS Dial In services: - “DiD” “IVR” “Phonebook” Direct outwards dialing of a 3G handset. Dialing 3G terminals via selection menu. Selecting entry from gateway phonebook Any of these services can be enabled or disabled, but at least one must be enabled for incoming call routing to take place. In order to enable parallel incoming calls, a PRI number range must be defined.
5 Configure the Gateway Example: A videoconferencing system calls into the Extension Dial In number with IVR active. The gateway activates the ‘Welcome’ picture and sound. The videoconferencing system enters the extension (H.323 Alias) followed by the # (pound-sign) to indicate end of number. The gateway starts to call the IP endpoint and the “Connecting” picture and sound are activated. When the call is connected audio and video are transmitted through the gateway.
TANDBERG 3G Gateway User Manual Example: An UMTS phone calls into the Extension Dial In number with IVR phonebook active. The gateway shows a menu with makes it possible to submit the name (both Christian and first name) via the alphanumeric DTRMF keys .
