VoIP (Voice over Internet Protocol) is a process that entails conversion of analog voice signals into digital data that is transmitted over the Internet.
By using VoIP, you get to communicate, just like over a traditional telephone, free of cost. It is possible because by using the Internet, people are getting around the telecom operators. This feature is attracting people and is increasing its adoption exponentially by enterprises and individual users alike.
As hands-free mobile phones have made conventional phones outdated, VoIP is transforming the way we communicate. But before we get swayed away by VoIP, there are certain downsides associated with this technology.
Voice quality can deter you, sometimes, from using VoIP for all types of calls. The quality of voice suffers mainly due to bandwidth reasons. Problem with this technology is that data is compressed in order to be delivered before it is decompressed when it reaches the recipient of the call. It must be also ensured that broadband connection is not being shared with other communication applications. Besides choosing a good provider, users also need to ensure that the quality of their hardware is reasonably good.
Another problem with VoIP is its overdependence on the bandwidth of a connection. If the connection is down, VoIP also becomes non-functional. If your broadband connection is not functioning at its optimal quality, then the clarity of voice will not be as good as that of public switched telephone network (PSTN). Needless to say, people using dial-up connections should not be expecting good clarity while using VoIP.
Within an organization, a VoIP is installed on a broadband connection, which in all likelihood will be used for other data requirements, such as emails, downloads, streaming, etc. In that case, VoIP’s functioning could be affected, especially at peak times. When multiple users’ access the connection, it would be difficult to gauge how many users would be online at any particular given point of time. Therefore, VoIP cannot be assured of the bandwidth it needs at times. At such times, companies, therefore, need to reduce Internet connection for other applications in order for voice calls to be made satisfactorily.
VoIP is also dependent on power, which means that VoIP hardware, like ATA, a phone adapter, router, modem, etc. have to be plugged to the electric power supply for it to function.
In addition to all of these, as VoIP functions over the Internet, it can be affected by viruses, malwares, cyber-attacks, etc. Moreover, these threats can take place at any time and could act as hurdles for business needs of an enterprise.
