Technology can save a lot of phone calls on the cost, whether you are a Consumption Persons, small business owner, or a large enterprise. In fact, if you frequently make long distance, then, using VoIP can reduce your telephone costs by up to hundreds or even thousands of dollars per month. Why, then, traditional telephone lines were still there? Why is not everyone using VoIP?
I have a group of SME managers chatted and understood that they are most concerned about?? In fact, the reason they generally do not use VoIP for only one reason?? Reliability.
Telephone company a reputation for reliability. Customers used to pick up every time Telephone When the dial tone. They used to call going through to the other side. At the same time they also used a clear voice, until the other party hang up. They do not like to settle for less.
Problems using VoIP These people when VoIP first became available, we’ve tried. And they have not given up the traditional public telephone system ( PS TN) to use IP phones, the reason is that they think VoIP to be entirely trustworthy. A user reported that, IP phones up very well?? Only at certain times. The rest of the time, every time he picked up the telephone, will find that there is no dial tone, so he had to re-play VoIP device to make and receive normal telephone. Another user said that the vast majority of the phone no problem, but calls to certain phone numbers, particularly those corporate PBX systems, generated a lot of echo, so that she had to call in and these people in exchange for traditional public telephone line. Also, there are totally weird problem reports, such as caller ID numbers and real numbers are totally different. Overall then, it was agreed that: VoIP has great potential, as function of cool Beta Test Software, but still a little away from the daily application of a distance to go.
In fact, complaints about VoIP?? Voice of poor quality, dropped calls, Service Intermittent failure?? Basically Mobile Phone operator, the initial Haowuerzhi; In fact, in the early development of the entire telephone system, the traditional public telephone network suffered the same complaints. This at least gives us hope?? As VoIP technology becomes more sophisticated, these problems will become less.
VoIP features VoIP due to its characteristics, resulting in some of the factors that reduce the reliability of VoIP. The traditional public telephone system using circuit switching; This means that the duration of any particular telephone call, the caller and receiver from beginning to end the existence of a dedicated circuit. In the call for the time, no one else can use the dedicated circuit.
VoIP calls are packet-switched network?? Internet (Internet access). Does not have a fixed connection actually exists. In fact, VoIP signal is digitized and broken into small pieces (packets), then through a series of Router Eventually reach the recipient. Different packets may take different paths to reach the destination, and then re-integrate. Multiple Communication (Voice or data) can share the same physical line. As the signal data will automatically choose the most unobstructed transmission line, the transmission more efficient and less costly. However, the data packets may also be lost or go the wrong way routes, Internet routers can greatly affect your call quality, regardless of whether the packet really adopted it.
VoIP rely on what Another public telephone network is more reliable because of its power supply independence. The company or at home use cordless phones, your equipment (automatic Switch Telephone station, etc.) may need to Electricity . But in fact, do not you just use the phone is to supply extra. They take their own electricity from the central office, so when you at home or electrical outage, you can still use the phone as usual.
But your VoIP line is dependent on the equipment is to be a power supply. If you lose power, your VoIP line goes down. Same time, it depends on your Internet connection. If your network is broken, so that voice data coming towards you lose the target. Even if only broadband network average momentary “glitches” will lead to transmission errors, which led to interruption of your phone. In addition, of course, those such as viruses, worms, hackers attacks will affect the Network Security Behavior, will also interrupt your IP phone calls. Improve the reliability of VoIP
By selecting a VoIP provider, large enterprise, you can avoid most of the problems mentioned above. But if you only have a small business can not afford to go from here? Fortunately, you can take to make your VoIP calls more reliable, even if you use just one low price (you can afford), for the ordinary consumer VoIP provider. These measures include:
Backup power ( UPS And Generator ) This can be sustained in the event of power failure for your VoIP equipment and Internet routers to provide electricity.
Redundant Internet Connection You can use some routers, the two different Internet providers with integrated network bandwidth, so even if one of the failures occurred, your network can still make.
For the dedicated Internet connection for VoIP
Your VoIP lines and normal data network separate from, and use special Firewall For protection, which allows you to avoid the spread of the virus via the data network attack or other malicious attacks. You can configure the firewall in addition to a particular VoIP protocol, the other prohibiting all communication.
Redundant VoIP lines If you need to use multiple phone lines, you do not have to buy all from the same provider. Although the same number of different providers may choose to use the more convenient, the price will be lower, but the main benefit is in one of these providers, failure, and will not cause your phone line a total standstill.
