No matter which business you are running, to be able to get the fullest output you should be relying on the VoIP usage. Like any other technology VoIP has many advantages that is attracting people from all over the world and from any size and type of business to implement the use of VoIP systems. Some of the benefits of VoIP are as follows.

Advantages:

1.Cost Reduction: The VoIP implementation means lowering the total cost of operations and maintenance of the telephony. The cost of both the data and the voice networks are lowered with the usage of IP telephony.
2.Simplification: The equipment and wiring costs are further lowered by the use of integrated systems. As the communication is made through a single wire the systems are more simplified but efficient.
3.Less Complex: The overall implementation of the IP telephony systems universally allows the system to be less complex.
4.Advanced Features: The advance feature like video conferencing and tele presence is done by the integration of data and voice over the same medium. This increases the efficiency of the overall system.
5.Lower Call Rates: The VoIP enables all the international calling to be performed at a lower call rates. The calls are cheaper than the local existing PSTN calls.
6.Mobile System: The IP Telephony is done via MAC addressing thus the system is mobile; it can be plugged anywhere in the network.
7.Flexible: The system makes sure that the voice can be delivered any where in the world regardless of the media the other side is using.
8.Increased Bandwidth: The high data rates makes it efficient to deliver voice using less bandwidth.

Disadvantages:

Like any other thing in this world VoIP also has some disadvantages regardless of its vast benefits.

1.VoIP telephones are still dependent on the wall power. This means that if there is no power the VoIP phones are useless. They can’t function when there is no power. The system uses the phantom power provided by the central office. If there is no power the traditional phones still works but VoIP systems need to be more stable when it comes to the power source.
2.VoIP systems can’t be integrated with the digital videed with the digital video recorders and security systems. Although all these syslthough all these systems use the phone lines but they can’t be integrated into the VoIP system.
3.In case of emergency VoIP calls are not very reliable. In some cases these calls might not function as we want them to and thus a local phone line serves the best.
4.VoIP systems are susceptible to different factors like call packet loss, jitter and latency. These factors lower the call quality. Also the VoIP systems can easily be attacked by viruses and hackings.
