Despite some definitive advantages over PSTN, VoIP is not free from
drawbacks as it is in its nascent phase. There are basically, two major
problems with the VoIP such as: 
Power Supply - In case of VOIP, if you lose power, the line goes down.
Besides, the quality of internet connection also decides the quality of
calls as well – if the internet connection goes down, you will be 
facing
problems to make or receive calls. Further, the transmission errors,
viruse threats and hack attacks can considerably bring down the network
which affects the calling experience.
Performance - Calls in VOIP are routed through PBX systems and hence,
the quality of the PBX systems decides the quality of the calling as
well. Some users who have tried VOIP have negative experience about its
reliability. For instance, sometimes the users would pick up the phone
to find no dial tone and they would have to reboot the VOIP box before
making or receiving a call. Similarly, other problems such as defective
call ID reporting and much echo during the phone calls have contributed
the popular disapproval of the VOIP as an alternative the existing PSTN
system.

In addition to above some more limitations of VOIP are:
1. VOIP voice quality: The voice quality is not the best using VOIP.
2. VOIP is highly dependent on Bandwidth: Lower the bandwidth lower is 
the quality of using VOIP.
3. Connect Down: Since VOIP is dependent on Bandwidth if the same goes 
down the connect goes down.
4. Shared Connection: If in a corporate you are using VOIP on shared 
connection the quality suffers.
5. VOIP Needs Power: Thus a failure in power will result in loss of 
VOIP connection.
6. Security: The security is not the best and it can be hacked thus 
making it prone to security issues.
