VoIP systems interface with traditional public switched telephone network (PSTN) allowing for transparent phone communications worldwide.

VoIP systems employ session control protocols to control the set-up and tear-down of calls as well as audio codecs which encode speech allowing transmission over an IP network as digital audio via an audio stream. Codec use is varied between different implementations of VoIP (and often a range of codecs are used); some implementations rely on narrowband and compressed speech, while others support high fidelity stereo codecs.

Voice over Internet Protocol (VoIP) is a general term for a family of transmission technologies for delivery of voice communications over IP networks such as the Internet or other packet-switched networks. Other terms frequently encountered and synonymous with VoIP are IP telephony, Internet telephony, voice over broadband (VoBB), broadband telephony, and broadband phone.

Types of VoIP Service

  • SIP trunking is a Voice over Internet Protocol (VoIP) and streaming media service based on the Session Initiation Protocol (SIP)[1] by which Internet telephony service providers (ITSPs) deliver telephone services  to customers equipped with SIP-based telephone systems and servers.
  • Hosted/Cloud based VoIP Phone System:
    A hosted system exists online and you the customer do not “own” the service. Usually, you are instructed to buy your own desk phones (usually from the service provider). The “Hosted” service provider is responsible for the upkeep of your system and making sure it stays online.
    Internet bandwidth stability is very important with this type of service because when the internet goes down, so does all your phones.
    Hosted PBX is a service where the call platform and PBX features are hosted at the service provider location. The business end users connect via IP to the provider for voice service.
