How reliable and secure is VoIP?
VoIP is as reliable as the Internet. Most of the reliability issues of VoIP have to do with either an individual service provider or the VoIP equipment that you may be using. There are several problems that you can run into due to bad installation or misconfiguration. VoIP is also secure just like a traditional phone service. With encryption, VoIP calls can be even more secure than those placed over traditional phone lines.
