H.323 Addressing
IP ADDRESS Endpoints may call directly to other
endpoints using IP addresses or call indirectly
through a gatekeeper. ALIAS Endpoints may
establish a connection with other endpoints by
using an alphanumeric alias which is translated
to an IP address by a gatekeeper. E164 (Telephone
Number) Endpoints may establish a connection with
other endpoints by using a numeric value known as
the E164 address. This must be translated by a
gatekeeper into an IP address.

GATEKEEPERS
14
What is a Gatekeeper?
A gatekeeper as defined by the
ITU
-T H.323 standards
is an optional device that provides access and
bandwidth usage controls for H.323 devices on an
IP
network.
May also provide address lookup and translation,
conference accounting, and site/conference status
information.
It is the key element in the network that allows
endpoints to find other endpoints, gateways, and
to
join
multipoint
conferences

Gateway Connection - H.320 To H.323
MULTI-SUBSCRIBER NUMBERING (MSN) A single ISDN
B-Channel can be assigned several unique ISDN
numbers. When any of these numbers is called, the
call will arrive on that channel. The called
number will be contained in the setup message
which can then be used to identify the
destination H.323 entity. ISDN SUB-ADDRESSING When
an ISDN call is made, an additional set of
digits may be added to the end of the ISDN
number. This is the Sub-Address and will be
delivered to the destination channel with this
information in the setup message which can then
be used to identify the destination H.323
entity.
24
Gateway Connection - H.320 to H.323
INTERACTIVE VOICE RESPONSE (IVR) DUAL TONE
MULTI-FREQUENCY SIGNALLING (DTMF) A gateway can
receive an incoming call from an H.320 terminal
and establish the connection autonomously. Audio
information may be sent to the H.320 terminal
which can then be controlled in a menu fashion by
DTMF tones from the H.320 terminal - this can
either lead to a connection being established
with an H.323 endpoint via the menu or a
gathering of DTMF digits that can be used to
identify a destination H.323 endpoint. TERMINAL
CONTROL STRINGS (TCS-4) This method, once again,
requires the Gateway to establish an autonomous
connection with the calling H.320 terminal.
During the capability negotiation phase, the
H.320 terminal can send a TCS-4 string containing
information that can be used to identify the
H.323 destination.
