VoIP service providers seem to be failing to keep up with the demands of more and more subscribers, according to a new study released recently by Brix Networks, a seller of network service equipment. Using data from more than 1 millions uses of the company's ?TestYourVoIP.com? quality testing website, Brix has concluded that typical VoIP telephone call quality has declined by nearly 20% over the past 18 months. VoIP technology is very susceptible to problems with latency (time delay in data delivery), packet loss, and other quality issues. Since voice communication is so time-sensitive, it is very difficult to carry on a conversation when clipping and other issues arise. Consumers considering making the switch to VoIP should keep the results of the Brix study in mind when making the decision. For consumers who already use their broadband connection for other uses, VoIP continues to be an attractive option from a cost point of view. However, a vary eye should be kept on service quality, as it can quickly render any cost savings meaningless if one pays for a service that doesn't work. When shopping for VoIP service, consumers should be sure to ask their customer service representative what their company's average ACQ (acceptable call quality) is. Anything below 80% should raise a red flag.
