In the early years of Voice over IP phones, sound quality was a major issue; in recent years, however, data transmission has improved to the point that VOIP conservations are as clear as standard phone lines with the right connection. For individuals and businesses with fast internet connections, VOIP voice quality is top flight and the additional features in Internet phone dialing make it superior to traditional land lines in many cases.
The first, and most important, factor to consider is the speed of your Internet connection. In order to reduce latency on your VOIP calls, a simultaneous, fast broadband connection is necessary at all times. The ideal connection is a T1 or T3 line which provides fast packet transmission; although a quality cable or DSL modem can also suffice for most personal uses. Consider upgrading your Internet connection if you’re relying upon VOIP to provide you phone service.
If you have a modern VOIP phone and gateway, then your voice quality should be as good as a standard phone (and likely better than your cellular provider.) Always consider the reach of your Internet connection, as wireless VOIP phones require you to be in proper range to your router. Many phones also require you to speak clearly and directly into the phone, so that the voice data is captured properly. With advances in technology, the voice transmission on VOIP will allow you to have seamless, high quality conservations with friends , family and business associates in real time without worry.
