Key Name Description
h323_default_gateway
Indicates the IP address of a default gateway to use for outbound calls. If a user only
specifies a phone number when making an H.323 call and the application is not using an
H.323 gatekeeper, the API forwards the call to the gateway specified with this parameter.
The API forwards the specified phone number to the gateway for routing purposes. When
set, this parameter must contain an IP address in the form:
xxx.xxx.xxx.xxx:PortNumber(Port number is optional)
Examples
10.128.22.6:1720 (port number specified)
10.128.22.6 (no port number specified)
Note: For the H.323 protocol, the port defaults to 1720 if not specified.
Range: 1-255 characters
Value Type: character string (up to 256 characters)
Default value: <blank>(empty string indicating no default gateway defined)
Note: The API does not use this parameter if the configuration file specifies a value of 1 for
the h323_register parameter (see below).
h323_e164alias
Specifies the E.164 alias of the H.323 terminal. The system uses this alias during
gatekeeper registration and call establishment. The alias identifies the phone number of
the H.323 terminal.
Range: 1 - 128characters (inclusive)
Value Type: character string restricted to numbers 0 through 9 and the star (*) and pound
(#) symbols
Default value: <blank>
h323_gatekeeper_id
Specifies the ID of the H.323 gatekeeper that the H.323 terminal expects to find during the
gatekeeper discovery routine. If you do not set this parameter, the H.323 terminal attempts
to register with the first gatekeeper it finds.
<blank> Uses the first gatekeeper the H.323 terminal locates.
Value Type: Unicode character string (up to 256 characters)
Default value: <blank>
h323_gatekeeper_
ip_address
Specifies the IP address of the H.323 gatekeeper that receives the registration request
from the H.323 terminal. If you leave this parameter blank, the H.323 terminal performs a
multicast gatekeeper discovery routine to find the gatekeeper using port number 1719.
xxx.xxx.xxx.xxx Configures the system to use the specified H.323 gatekeeper. Set
the gatekeeper IP address in the form: xxx.xxx.xxx.xxx:PortNumber
<blank> Configures the system to use a multicast process to discover the H.323
gatekeeper.
Value Type: dotted decimal
Default value: <blank> (uses multicast discovery process and port number 1719)
h323_gatekeeper_ttl
Specifies the number of seconds to allow between registration request messages sent
from the H.323 terminal to the gatekeeper. After reaching this limit, the H.323 terminal
generates another registration request to the gatekeeper because the system now
considers the previous request invalid.
