| In general, phone service via VoIP is free or costs less than equivalent service from traditional sources. Some cost savings may be attributed due to using a single network to carry voice and data. VoIP to VoIP phone calls on any provider are typically free, whilst VoIP to PSTN calls generally costs the VoIP user.
Functionality
VoIP may help to facilitate communication system tasks that may be more difficult to achieve using traditional phone networks:
- Incoming phone calls can be automatically routed to your VoIP phone, regardless of where you are connected to the network.
- Take your VoIP phone with you on a trip, and anywhere you connect to the Internet, you can receive incoming calls.
- Free phone numbers for use with VoIP are available in the USA, UK and other countries from organizations such as VoIP User.
- Call center agents using VoIP phones can work from anywhere with a sufficiently fast Internet connection.
