VoIP with Dial-Up
It is true that a broadband connection will give you more consistent, reliable VoIP call quality, but similar results can be obtained using a dial up account if some guidelines are followed.
First of all, it is important to note that all VoIP service providers are different i.e., all of them do not support dial-up users. For instance, companies such as Vonage back away from dial up connections. However, the providers that do support dial up usually only support dial-up above certain speeds. The two most popular companies that do support dial up VoIP are Callserve and Go2Call. To make a good voiip call with dial-up, close all the programs that are running in the background to get higher call quality. If you are using Windows, just right click & close all open non-essential applications that are shown in your taskbar at the bottom right of your screen. If you are using Windows XP & there are other users logged on, be sure they log off before trying to make a call. Other activities that will compete for bandwith with your VoIP call are: Instant Messaging, checking your email, web cameras, surfing the internet or downloading anything. Scan your system frequently for Viruses and Adware, these programs can tie up your browser and internet connection, slow down your system and affect your call quality. Use a headset with a boom microphone and this should eliminate annoying voice echoes often associated with VoIP phone calls. If you use a headset, voice signals are limited in volume and thus the chances of your microphone re-transmitting those voice signals is greatly reduced. Thus, following these guidelines you can enjoy VoIP with dial-up connection also.
