What's the difference between hosted PBX and SIP trunking


Voice over internet protocol — or VoIP — telecommunication has skyrocketed in popularity among businesses since it gained enough acceptance within the early 2000s, and for good reason. Internet-based phone systems are way more customizable than ancient networks. They need considerably less investment in hardware and infrastructure, they update automatically through software package, they can unify communications by providing electronic messaging, voice, video and chat in one platform.


Private branch exchange, or PBX, was originally developed by non-public corporations trying to avoid wasting cash on internal calling by switching the circuits themselves regionally at a time once human operators still ran switchboards manually. This removed the requirement for a third-party supplier to route internal calls, however it needed businesses to finance, build and maintain the inner network themselves.

Cloud Hosted PBX

Even smaller businesses will currently maintain a personal internal calling system by farming out the infrastructure and hardware needs to a PBX host. Cloud Hosted PBX follows constant plan of handling internal calls domestically, however by hiring a third-party host to run the system. With cloud hosted PBX, the responsibility of owning, operating, securing and maintaining the required hardware — that is pricey and difficult — is far away from the business, allowing its personnel to target their core competence.

Why Businesses choose cloud hosted PBX

Also, over one person may be reached through one variety, and cloud PBX directs, holds and transfers calls. Since the system is hosted by an independent firm that owns and maintains the hardware, there are lowest start-up prices. Also, once the host upgrades its system, those upgrades are passed on to the consumer business at no additional charge.

SIP Trunking

Unlike the long, storied history of PBX, Session initiation protocol, or SIP Trunking, may be a far more recent invention. Developed at the dawn of the of Internet's public arrival in 1996, SIP modernized the PBX idea. The crucial distinction between SIP Trunking and cloud PBX hosting is that SIP permits many types of media (audio and video, for example) to be channeled through identical line by replacing the standard trunk with the net.

Why Businesses choose SIP Trunking

SIP offers everything that comes with cloud hosted PBX, however it improves efficiency and quality through a sophisticated system that removes primary and basic-rate interfaces. Users will communicate with both mobile and fixed callers from basically anyplace, and price efficiency is improved by consolidating audio and video into one line.
