The Main VoIP Disadvantages:
Dependence On Power And Internet
One of the main VoIP disadvantages or limitations is that VoIP Telephony needs both power and internet to work. When the power goes out, you don’t have VoIP.
The same thing occurs when your ISP (Internet Service Provider) doesn’t have power or is down for maintenance. In this situation, if you don’t have an additional landline phone, you are left with no means of communication with the outside world.
Here is where the traditional phone line scores over the VoIP telephone system. Even when there is no power in your house or office, your traditional landline phone works as it is powered by the electricity at the phone company.
Power outage may not be much of a problem if it is for a shortPower outage may not be much of a problem if it is for a short duration, but this can cause severe difficulty if you want to make an emergency call during this time. One way to get around this problem is to have a back up power system - universal power supply – or maintain a regular landline phone for such emergency situations.
Another area where your traditional phone has advantage over the VoIP telephone is that when you dial 911 on it, you are immediately connected to the nearest PSAP (PublicSafety Answering Point), a physical location where 911 emergency telephone calls are received and then routed to the proper emergency services.
Inability to make 911 calls on VoIP phones was a serious issue, but this VoIP disadvantage has been largely overcome because now most VoIP service providers offer E911 feature with their services.
If emergency calling is your concern and if you plan to replace your landline phone with an internet phone, sign up with a service provider which provides acceptable E911 facility with its service.
Here the thing to remember is that even the best E911 service from your VoIP provider will be of no use when your internet connection goes down because your ISP has power outage or is down for maintenance.

- PC Power
One of the advantages of VoIP is that you can make a VoIP call and surf the internet at the same time. This can turn into a VoIP disadvantage if your pc has limited process capacity. Your call can be affected or totally crash if you are downloading a big file or running a program that needs lots of process power.
Still another VoIP disadvantage is that VoIP can suffer the same security threats that your pc does – viruses, identity theft, phising and spam. If you have been using your pc to surf the internet you know that there are ways to safeguard yourself against such threats. It is the same with VoIP. Here also you can certainly take a number of steps toward VoIP security and enjoy the many benefits of VoIP.
