Description
V2 GW Prefixes
H.323 Version 2 enables the gateway to specify prefixes that
the user should dial before 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.
