25.4 Configure Registration Authentication Service (RAS)
in an H.323 Gateway
As mentioned in previous chapters a call setup can use
direct call signaling
and
gatekeeper routed call
signaling
. Direct call signaling is already described in Chapter 21, “CS Interface Configuration”. For
gatekeeper routed call signaling the H.323 network needs a gatekeeper device. Gatekeepers manage
H.323 zones, which are logical collections of devices such as all H.323 devices within an IP subnet.
Gatekeepers for example provide address translation (routing) for the devices in their zone. This
could be, for instance, the translation between internal and external numbering systems. Another
important function for gatekeepers is providing admission control, specifying what devices can call
what numbers.
To use the gatekeeper the SmartNode has to 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 21, “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.
Note:
If you have to change the call signalling 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
.
