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.
