SmartWare Software Configuration Guide 39 • SIP interface configuration

Introduction

This chapter provides an overview of SIP interfaces used by context 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. See Chapter 33, “CS interface configuration” on page 381 for information about configuring basic CS interfaces.

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 context SIP gateway (see Figure 60).

Figure 60. SIP interfaces on the CS context

A SIP interface is a CS interface type that is responsible for the address translation between the SIP environ- ment and the call control. It provides configurable translation rules that define which parameter of which SIP header has to be translated to call control properties and vice versa. In addition, it offers VoIP settings and the possibility to configure SIP supplementary services like Call Transfer, Call Reroute or Session Timer. All SIP interfaces must be explicitly bound to a context SIP gateway. Calls that are routed from the Context CS to one of the SIP interfaces will be forwarded for call establishment to the context SIP gateway to which the SIP inter- face is bound. All of the parameters configured in the SIP interface will be applied to the forwarded call.

SIP interface configuration task list

This section describes the configuration tasks for SIP interfaces listed below. You must at least perform the tasks that are not marked as optional to define a working SIP interface. The optional tasks are 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 33, “CS interface configuration” on page 381.
