${h323_e164} - RealPresence Resource Manager accepts this value to automatically configure
the parameter.
voIpProt.H323.enable
Enables or disables the ability for your system to use the H.323 protocol.
You must set to "1" to use other voIpProt.H323.* parameters.
If set to "0", you can't also set voIpProt.SIP.enable="0".
0 (default)
1
voIpProt.H323.gk.auth.enable
Enables support for H.235 Annex D Authentication.
When H.235 Annex D Authentication is enabled, the H.323 gatekeeper ensures that only trusted
H.323 endpoints can access the gatekeeper.
To use this parameter, you should set voIpProt.H323.gk.mode="Specify".
0 (default)
1
voIpProt.H323.gk.auth.password
Specifies a password if authentication is required for registering with the gatekeeper.
To use this parameter, you should set voIpProt.H323.gk.mode="Specify" and
voIpProt.H323.gk.auth.enable="1".
String
voIpProt.H323.gk.auth.userId
Specifies a username if authentication is required for registering with the gatekeeper.
To use this parameter, you should set voIpProt.H323.gk.mode="Specify" and
voIpProt.H323.gk.auth.enable="1".
String (0-62)
voIpProt.H323.gk.ipAddress
The gatekeeper IPv4 address the system registers with.
As part of the registration process, the gatekeeper might return alternate gatekeepers. If
communication with the primary gatekeeper is lost, your system registers with the alternate
gatekeeper but continues to poll the primary gatekeeper. If the system re-establishes
communication with the primary gatekeeper, it unregisters from the alternate gatekeeper.
What you can set here is determined by how you've configured voIpProt.H323.gk.mode:
Off - Setting the gatekeeper IP address isn't needed.
Auto - Setting the gatekeeper IP address isn't needed.
Specify - Enter the gatekeeper IP address or name (e.g., 10.11.12.13 or
gatekeeper.companyname.usa.com).
String (0-255)
voIpProt.H323.gk.mode
Specifies if you want to use a gatekeeper for H.323 services.
Off (default) - Calls do not use a gatekeeper.
