Voice over IP. The capability to carry normal telephony-style voice over an 
IP-based Internet with POTS-like functionality, reliability, and voice quality. 
VoIP enables a router to carry voice traffic (for example, telephone calls and 
faxes) over an IP network. In VoIP, the digital signal processor (DSP) 
segments the voice signal into frames, which then are coupled in groups of 
two and stored in voice packets. These voice packets are transported using IP 
in compliance with ITU-T specification H.323.
