SIP trunking vs. VoIP? How do the two compare?
SIP and VoIP actually work together to create a robust cloud-hosted communications solution. Both SIP and VoIP depend on protocols, which are technology rules and parameters that enable digital devices, phone systems and computers to communicate. Voice over internet protocol is the basis for voice calling on an internet phone system. Adding session initiation protocol, or SIP, allows the transmittal of voice, data or video. Together they are two pieces of the IP telephony puzzle.
