VoIP Drawbacks

Although VoIP is a fantastic communication solution in many ways...there are some drawbacks that still need to be worked on.

Location and 911

It is an issue regarding pinpointing the geographic location of an IP address. In VoIP the call information is provided via an IP address. This is necessary in the case of emergency calls. Although some VoIP providers now do have call routing based from a specified address. And additionally, some have implemented a system known as E911, a more advanced version of the US emergency 911 system, which provides additional location data over VoIP to emergency responders, including street address and the floor inside a building.


One challenge to maintaining call quality is bandwidth: high quality sound requires quite a bit of it. The technology to compress audio and to reconstruct it has been improved to the point where VoIP sound quality over a high-bandwidth connection is as good as or better than that of regular phones. But some networks that are fine for data are not up to the demands of VoIP.

Another limitation of the voice over internet protocol is the inability to use these lines for fax capabilities and a difficulty downloading electronic program that guides to personal video recorder products (such as TiVO). Since VoIP runs through a computer, it does not function independently, meaning that VoIP will not function during a power outage, whereas regular analog telephones do that. Many have made the argument that until VoIP is capable of offering 'all' services that PSTN can offer, that they will not be making the switch.

VoIP security issue

The legal and security issue is another drawback of the voice over internet protocol. Being the mater of information technology and cyber world what are the law exit are not sufficient to meet the legal and security issues.

VoIP Process

Unlike regular phone systems that get set up and basically forgotten, VoIP systems require more attention.

Like any software application, your VoIP server will require occasional upgrades and maintenance.

Network Dependency

Since regular phones get all the power they need through the phone line, they continue to work if there is a power outage. In contrast, most VoIP phones need to be plugged into a power source to work. By definition, VoIP phones are also network-dependent.

To businesses where phone service is absolutely critical, this can be a concern since computer networks can occasionally be brought down by a server crash or other problem. However a good IT staff can prevent most outages and react quickly when one occurs.
