|
 VoIP technology does not require a theory of broadband Internet access, but the results obtained by means of modem links are not satisfactory. More and more households access the Internet via DSL which requires a traditional phone line. The need to incur charges for VoIP and an additional fee for telephone and Internet access to significantly reduce the benefits. VoIP can also be used on the basis of the internet cable (supplied by the cable) or with the use of the residential network. In this way you can totally independence away from traditional phone line but not on charges for access to the Internet.
* Quality link
For VoIP is not only important but also the quality of transport links. If packets are delayed or loses, the voice can be picked or distorted. This applies to congested network, or with poor quality of infrastructure (such as connections to a large distance from the switch / router, poor quality cables and sockets, cable between the lines).
* Reliability
Conventional telephones are connected directly to telephone lines belonging to the telecommunications company. In the case of black-out (power outage,) a traditional phone line still works and it is possible to perform and receive calls. Even telephones that require extra power is so constructed that in case of power failure receiving calls, manual dialing telephone ringing and the other is still possible. In the case of all the elements of VoIP telephony network (DSL modem / cable, router, Gateway IP, IP phone, computer) no longer function. To preserve the functionality of the system is necessary to maintain the system voltage in the form of emergency power supplies, UPS or generators. However, in the case of Internet access through the residential network, we can not have at the end of the impact of the continuous access to the Internet in such a situation.
* The cost of equipment
The equipment required to access the VoIP calls are more expensive than traditional telephones. Prices are cheapest in the range of goals ranging from 200 to 260 gold, the upper limit of niesposób determined. To this you add the cost of a traditional telephone. Cheapest VoIP phones alone cost 260 gold ok. Price of brand and more technologically advanced models can be several times higher. You can buy a cheap USB phone. Even less cost to the normal headset with microphone headset. They need to work integrated into the computer.
* Emergency calls
Nature of the internet makes it difficult location. This makes it difficult to redirect the caller to the nearest help center. It may therefore be that we will not be allowed by the IP phone call the fire brigade, ambulance or police. Currently, work on solution this issue especially since the U.S. and other governments of the countries heavily pushed for VoIP operators, but for now the effects are not yet satisfactory. Simplest board to direct dial the emergency numbers, including numbers for country and the city (you can store them in memory device using the speed dial) and do not use numbers 9xx and 112. |
