5.1 INTRODUCTION TO VOIP

The TalkSwitch with VoIP lines is a hybrid PSTN/VoIP phone system. The addition of VoIP to the TalkSwitch product line adds the ability to use a broadband IP connection for voice calls.

The VoIP enabled TalkSwitch can be used in many different applications. The most popular configurations are multi-branch, teleworker integration and service provider integration.

5.2 OPTIMIZING YOUR IP NETWORK FOR VOIP

5.2.1 The Broadband Connection

For optimum quality of VoIP calls on your system, we recommend that you subscribe to a high-speed broadband connection from your Service Provider. ‘Lite’ broadband connections (typically 128 Kbps downstream and 64 Kbps upstream) are not suitable for simultaneous voice and data traffic. The limiting factor for a broadband connection is the upstream bandwidth to the Internet Service Provider.
