Voice over IP

Akronim: VoIP

VoIP
Voice over IP. Sending voice data (i.e. human conversations) using IP
packets across a network (such as the internet) instead of across a
(traditional) telephone network.
A number of companies offer VoIP services. Typically these provide
free telephone calls between people using the same software, but do not
support calls between people using different software. Some provide
additional facilities such as VoIP to landline numbers (call-out) or
landline numbers to VoIP (call-in), and video.
