So you've heard that you can use your computer to make cheap long-distance calls over
Internet. Maybe you've even tried it. Chances are though that if you've attempted VoIP calls over a dial-up connection, you've experienced intermittent quality, 'call drop-outs' and annoying speech transmission delays. The good news is that there are some quick, easy steps that you can take to dramatically improve
quality of your VoIP calls over dial-up connections.There's a lot of hype these days surrounding Internet-based voice communications (VoIP) replacing traditional telephone service. Most of this revolves around companies such as Vonage who coin themselves as
'Broadband Phone Company'. So what about those of us who don't have a broadband connection? Just because you don't have high speed Internet, doesn't mean that you can't save a fortune by using VoIP for your long-distance calls. Whilst a broadband connection will usually result in more consistent VoIP call quality, comparable results can be achieved using a dial-up connection provided some simple guidelines are followed.
Shop Around
Not all VoIP service providers support dial-up users. Companies such as Vonage bill themselves as alternatives to traditional telephone service and shy away from
dial-up community (who are tied to those 'traditional' networks to access
Internet). Furthermore, some service providers only support dial-up above a certain speed (e.g., 56Kbp). Two companies whose VoIP softphone applications work well over low speed connections include Callserve and Go2Call.
'Free-up' your System Resources
In order to ensure
highest call quality, close programs that are running in
'background'. For Windows users, these applications can be seen in
taskbar at
bottom right of your screen. 'Right-click'
icons and close those programs that aren't critical to system security (e.g., don't close anti-virus software, firewall applications and
like).
If you're using Windows XP with user switching enabled, log off all users except
one that will be used to make
call. This will prevent
other user identities from running software and/or using your bandwidth while you're making calls.
