Dial from IP
Dial from IP
IP endpoints and MCUs can call out through the gateway by using one of the H.323 services defined on the
gateway.
H.323 Services
H.323 Service prefixes are used for IP endpoints to
access the ISDN network. Up to twenty 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" (default).
•
The IP endpoint dials 067121212 to dial the ISDN number 67121212.
•
The gateway starts to call the ISDN endpoint and the "Call proceeding" picture and sound are activated.
•
Audio and video are transported through the gateway when the call is connected.
