Dialable address formats
The destination address that is entered using the caller’s endpoint can take a number of different formats,
and this affects the specific process that the VCS follows when attempting to locate the destination
endpoint. The address formats supported by the VCS are:
and this affects the specific process that the VCS follows when attempting to locate the destination

n
IP address, for example 10.44.10.1 or 3ffe:80ee:3706::10:35
n
H.323 ID, for example john.smith or john.smith@example.com (note that an H.323 ID can be
in the form of a URI)

n
E.164 alias, for example 441189876432 or 6432
n
URI, for example john.smith@example.com
n
ENUM, for example 441189876432 or 6432
Each of these address formats may require some configuration of the VCS in order for them to be
supported. These configuration requirements are described below.

Dialing by IP address
Dialing by IP address is necessary when the destination endpoint is not registered with any system
(such as a VCS, gatekeeper or Border Controller). See the

Endpoints registered to a VCS Expressway
Calls made by dialing the IP address of an H.323 endpoint registered directly with a VCS Expressway
are forced to route through the VCS Expressway. The call will therefore be subject to any restrictions
configured on that system.

Dialing by H.323 ID or E.164 alias
No special configuration is required to place a call using an H.323 ID or E.164 alias.
The VCS follows the usual
, applying any transforms and then searching the Local
Zone and external zones for the alias, according to the search rules.
Note: SIP endpoints always register using an AOR in the form of a URI. You are recommended to
ensure that H.323 endpoints also register with an H.323 ID in the form of a URI to facilitate interworking.

Dialing by H.323 or SIP URI
When a user places a call using URI dialing, they will typically dial name@example.com.
If the destination endpoint is locally registered or registered to a neighbor system, no special
configuration is required for the call to be placed. The VCS follows the usual
