No matter the average consumer, SME owners, or for large enterprises, almost everyone knows the Internet telephony (VoIP) can cut a large amount of telephone fee. In fact, the use of VoIP technology to make long distance calls a month can save hundreds, even thousands of dollars. Why, then, the traditional telephone lines still exist? Why not everyone is using VoIP technology?
Many SMEs discussed on this issue, what makes them most worried the use of VoIP technology issues can be summarized into one word: reliability.
Telecom companies are more reliable. Consumers are used to hear the dial tone every time they pick up the phone, dialing is 100% success and they are used to enjoy a clear call quality until hang up. Without such services, the consumer won’t drop PSTN and try VoIP.
That’s what we voipers should think over.
Problems of VoIP
Many businessmen tried the service as early as VoIP launched. But why they still insist to use PSTN is they do not feel that VoIP technology can 100% be trusted. Some users said that this technology was not poor on management, but the quality is often not stable enough. Sometimes you pick up the phone but cannot hear the dial tone, you have to restart the entire VoIP transceiver box and then can make call.
Some other users said, most of the phone calls are ok, but dramatic echo appeared when call enterprise extensions (some voipers claimed they can “eliminate the echo totally by NSM”---Sean, CEO, ECsino Tech co., Ltd, because they adopted new protocol—NSM, which is totally different from traditional protocol), so as to use PSTN when make this kind call. Even the number the receiver see actually is not the caller’s. These users told us: IP phone has great potential, but just like a lot of cool features of the beta version, but disable to maintain stability, so, difficult to use it daily.
As a matter of fact, complaining about the quality of VoIP: poor voice quality, interrupted connections, intermittent voice –seems like what has happened on mobile phone in early days, and also on PSTN. It allows us to have some confidence about VoIP, with the VoIP technology getting mature; these issues are expected to decrease gradually.
