What is IP Trunking?
IP trunking is large-scale, corporate, industrial or institutional use of VoIP. An entire organization hooks into the data world at large via one connection; that connection is then split among all the parties’ phones and computers. While VoIP is used in millions of homes, IP trunking is almost exclusively used by businesses because they’re the ones that have a need for multiple telephone lines and many telephony services (call waiting, voice mail systems, call forwarding, etc.), which are also carried via certain IP trunking services. At its core, IP trunking and VoIP is voice on data lines. That means that voices travel over the Internet as bits of data, not “voices” or electrical impulses as they do on a traditional, land-based telephone line. In addition to large data capacity methods like DSL and cable Internet, one of the ways IP trunking can handle multiple phone calls — as well as Internet data usage coming from multiple places on a forked communications network in one buildin
