VoIP stands for Voice Over Internet Protocol, a technology enabling a user to make voice calls over a broadband Internet connection. VoIP users can place calls to both analog phones and other VoIP users. The technology has both benefits and drawbacks compared to traditional copper phone lines.
VoIP offers features beyond what analog phones can provide including voicemail to email transcription, find me/follow me call routing and automatic call screening. Users may also be able to use VoIP to avoid paying for both an Internet connection and a traditional phone line.
Disadvantages of VoIP include the need for additional infrastructure and software, and its reliance on power and Internet connectivity. Another disadvantage includes the fact that emergency calls over VoIP are handled differently than over analog lines, potentially requiring a user to acclimate to new emergency procedures.
