Cheap Talk and Free Speech
Cheryl-Ann Tan

While Skype has its merits of being user-friendly and accessible to the less tech-savvy crowd, it has a few drawbacks. It is a peer-to-peer system, which means that a user might end up contributing a lot of traffic to the network—not an option for those who pay for internet by traffic (which is common in Russia). Other solutions are available which require combined software and services packages (microphone and headphones/speakers.

Here we will take a look at one of the protocols available to users — the Session Initiation Protocol (SIP), which transmits voice, and optionally, text and video—and how to make the most out of it.

First, download a software phone which supports SIP.

FireFly, free, user-friendly, supports various protocols www.tucows.com/preview/344929

X-Pro/X-Lite, paid and free versions, paid version has extended functionality including conference calling. Supports different platforms. Pocket PC version available. www.counterpath.com/index.php

Choose services to use with your phone. You need a service that provides incoming terminations (Calls from the Public Service Telephone Network/PSTN ) and outgoing terminations (Calls to PSTN). Some services provide free PC-to-PC calls.

Setup

When you sign up for a service, you are provided with a SIP proxy (domain), which you need to enter in your software phone settings, together with your username and password. Your software phone may support several codecs, which gives you an option to choose between the level of sound quality and/or bandwidth. Choose GSM if you are not sure of which one to use.

If you would not like to keep your computer on all the time, you might find it useful to purchase a hardware IP phone or internet router with VOIP support. Calls will be directed to your IP phone instead. These are available at D-Link (www.dlink.com).

Troubleshooting

Log on to the VOIP User forum at www.voipuser.org/forum_index.html and ask any question, but read the FAQ first!
