Good voice quality is essential for any business communication system. With the right configuration and a SIP vendor that uses Tier 1 carrier networks, SIP calls can be indistinguishable from calls made over traditional telephone lines. Factors that impact call quality include the amount of available internet bandwidth and the configuration of the router to enable QoS (Quality of Service), witch prioritizes voice activity over other data traffic.

The term encompasses a group of protocol technologies of which SIP is an example. In short, SIP is one of the specific protocols that enable VoIP.
