To use the gatekeeper the SmartNode has to register by the gatekeeper, therefore the Registration
Authentication Service (RAS) has to be enabled. The SmartNode has to register by a name or names,
therefore some aliases have to be specified. Furthermore the gatekeeper discovery could be specify
on automatically or manually.
Normally the remote IP address specified in the CS interface (refer to Chapter
25 , “ CS Interface
Configuration ”) is not set if gatekeeper routed call signaling is enabled, because the gatekeeper
supplies the remote destination IP address. Nevertheless the remote IP address is set in the CS
interface the call over this interface goes to the specified IP address but the gatekeeper will be asked
for permission.
Redundancy is of great importance in communications networks. An H.323 gatekeeper offers a
critical service in a network – failure of a single gatekeeper may result in non-availability of the voice
service in the entire network. The SmartNode allows configuring up to three different gatekeeper
addresses. These addresses are used for RAS in a round-robin fashion. Once communication with
one of the gatekeepers is lost the SmartNode falls back to the next address in the list. All entries from
the list can be removed by applying the no form of the command.
Note: If you have to change the call signaling port use the command 'call-signaling-port' in the H.323
gateway configuration mode. For more information refer to Chapter 20, “Gateway ISoIP Mode”, and
Chapter 21, “Gateway H.323 Mode” in the SmartWare
Software Configuration Guide .
Procedure
To enable the registration authentication service (RAS)
Mode
Gateway H.323
Command Purpose
Step 1 node (gw-h323)[h323]#gatekeeper-
discovery auto [gkid]
or
node (gw-h323)[h323]#gatekeeper-
discovery manual ip-address ip-port
[gkid]
Specify that the gatekeeper discovery has
to be done automatically
or
Specify the gatekeeper for the SmartNode
explicitly.
Step 2 node (gw-h323)[h323]#alias h323-id
name
or
node (gw-h323)[h323]#alias e164 number
Sets the identifier(s) for registration on the
gatekeeper with a string
or
with a phone number
Step 3
Repeat step 2 to add more that one alias to
the configuration.
Step 4 node (gw-h323)[h323]#ras Enable the RAS protocol for gatekeeper
registration and client resolution
Example: Configuring RAS
The following example shows how to configure the registration authentication service (RAS) for a
SmartNode in an H.323 network.
