SmartWare Software Configuration Guide 38 • H.323 interface configuration
Introduction
This chapter provides an overview of H.323 interfaces used by H.323 gateways and describes the specific tasks
involved in their configuration. This chapter does not explain the basic configuration steps required for all CS
interfaces. Information about basic interface configuration can be found in the general chapter about CS inter-
face configuration.
Within the CS context of SmartWare, an H.323 interface is a special type of CS interface providing call rout-
ing for incoming and outgoing calls to and from the H.323 gateway (see figure 59).
Figure 59. H.323 interfaces on the CS context
An H.323 interface is a CS interface type that also provides voice over IP settings in addition to the general CS
interface parameters. All H.323 interfaces must be explicitly bound to an H.323 gateway. Calls, which are
routed from the Context CS to one of the H.323 interfaces, will be forwarded for call establishment to the
H.323 gateway to which the H.323 interface is bound. All the parameters configured in the H.323 interface
will be applied to the forwarded call.
When a call arrives over H.323 in the H.323 gateway. The gateway looks for the best matching H.323 inter-
face, which is bound to that gateway. If there is an H.323 interface, which contains the IP address of the source
of the H.323 call in its remoteip configuration parameter, the call will be handed over to that interface for fur-
ther call processing. If no such interface is found, the gateway looks for an interface, which is bound to that
gateway and does not contain a remoteip parameter. If such an interface is found the call will be handed over to
that interface for further processing. If however such an interface is also not available, the call will be dropped.
H.323 interface configuration task list
This section describes the configuration tasks for H.323 interfaces listed below. You must at least perform the
tasks, which are not marked as optional, to define a working H.323 interface. The optional tasks are usually
only required in advanced configurations. Before you can start with the H.323 interface specific configuration
tasks, you need to create the H323 interface and define the routing for it as defined in chapter 33, “CS inter-
face configuration” on page 381.

• Configuring a remote IP address
• Using an alternate VoIP profile (optional)
