Other DSP applications
DSP resources are also required by TAPI-based telephony applications, such as voicemail.
Since TAPI applications and IP telephony cannot share the same DSP resource, you must
distribute the DSP resources between TAPI applications and IP telephony based on your
business requirements. See “Managing Wave system resources” on page 23-42 for more
information.
IP call routing
Call routing for IP telephony is similar to traditional call routing. This section assumes that you
are familiar with Wave call routing mechanisms. Chapter 29, “Understanding Wave Call
Routing,” provides information about how calls are routed in the Wave system.
For IP call routing configuration procedures, see “Configuring site-to-site call routing for IP
telephony” on page 6-3.
Signaling Control Points
A Signaling Control Point is an IP telephony endpoint that is capable of originating and
terminating IP calls. A Signaling Control Point is defined by an IP address and an IP telephony
signaling protocol. Its traditional Wave call routing counterpart is the trunk group.
Signaling Control Points can be substituted for trunk groups in any of your outbound call
routing scenarios. For inbound call routing, each Signaling Control Point configuration includes
an inbound call routing table where you can specify how to handle calls from each source.
Each Signaling Control Point configuration includes the remote Wave Server’s IP address,
signaling protocol, and call routing parameters. Once the Signaling Control Points are
configured you can include them as call destinations in your outbound call routing
configuration. See Chapter 29, “Understanding Wave Call Routing,” for information about
Wave call routing.
