User Guidelines

This appendix provides documentation for the use of the SPA products. It includes the following
sections:
•
•
The SPA can be configured to the custom requirements of the service provider, so that from the
subscriber point of view, the service behaves exactly as the service provider wishes, with varying
degrees of control left with the end user. This means that a service provider can leverage the
programmability of the SPA to offer sometimes subtle yet continually valuable and differentiated
services optimized for the network environment or target markets.
This chapter describes how some of the supported basic, enhanced, and supplementary services can be
implemented. The implementations described below are not the only way to achieve the desired service
behavior.

Placing telephone a call to another telephone or telephony system (IVR,
conference bridge, and so on). This is the most basic service.
When the user picks up the handset, the SPA provides dial tone and is ready
to collect dialing information via DTMF digits from the telephone touchtone
key pad.
Although it is possible to support overlapped dialing within the context of
SIP, the SPA collects a complete phone number and sends the full number in
a SIP INVITE message to the proxy server for further call processing. To
minimize dialing delay, the SPA maintains a dial plan and matches it against
the cumulative number entered by the user. The SPA also detects invalid
phone numbers not compatible with the dial plan and alerts the user via a
configurable tone (Reorder) or announcement.
Hang up the telephone.
