Introduction
This chapter provides an overview of SIP interfaces used by SIP 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, a SIP interface is a special type of CS interface providing call routing for incoming and
outgoing calls to and from the SIP gateway (see
A SIP interface is a CS interface type that also provides voice over IP settings in addition to the general CS
interface parameters. All SIP interfaces must be explicitly bound to a SIP gateway. Calls, which are routed from
the Context CS to one of the SIP interfaces, will be forwarded for call establishment to the SIP gateway to
which the SIP interface is bound. All the parameters configured in the SIP interface will be applied to the for-
warded call.
When a call arrives over SIP in the SIP gateway. The gateway looks for the best matching SIP interface, which
is bound to that gateway. If there is a SIP interface, which contains the IP address of the source of the SIP call
in its remote configuration parameter, the call will be handed over to that interface for further 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 remote parameter. If such an interface is found the call will be handed over to that interface for fur-
ther processing. If however such an interface is also not available, the call will be dropped.
SIP interface configuration task list
This section describes the configuration tasks for SIP interfaces listed below. You must at least perform the
tasks, which are not marked as optional, to define a working SIP interface. The optional tasks are usually only
required in advanced configurations. Before you can start with the SIP interface specific configuration tasks,
you need to create the SIP interface and define the routing for it as defined in chapter 27,
