GK Defined Services
Public
For any GK-defined service being used, the
user must select either “Default” or “Public.”
When Public is selected, the service is
accessible to all endpoints that are not part of
the zone.
V2 GW Prefixes H.323 Version 2 enables the gateway to
specify prefixes that the user should dial be-
fore the WAN number in order to make a call
using a certain medium. E.g., the user could
dial the prefix 3 for voice calls or 77 for H.320
video calls. The prefixes are defined in the
RRQ message at registration. Prefix can be
any H.323 alias, including an H.323 ID &
mail address.
When a terminal places a LAN to WAN call,
it should add one of the prefixes to the dialed
number. The Gatekeeper identifies the prefix
& routes the call to the appropriate gateway. If
more than one gateway supplies the same
prefix, line hunting is possible between the
gateways.
Prefix
Identifies the service. The prefix can be a
numeric code, alphanumeric string, name, or
phone number that the user dials. Per H.323
Vers. 2, prefixes can also be of URL and e-
mail type. Also for H.323 Vers. 2, the type
must precede the prefix. For example, TEL: 3
or NAME: John.
