What is Hosted Telephony

A guide to hosted telephony


The conventional way for a business to have a telephone system would be to get incoming lines from one of the many providers available, get a telephone system that connects to those lines and have individual extension’s connected to the system via either traditional telephone cabling or through structured cabling (CAT5/CAT6)

This is a tried and tested method and with the advent of what’s known as “converged technologies” ( the integration of telephony & IT products) provides a solid, reliable and very flexible solution for most businesses.

Hosted telephony takes away the telephone system hardware and hosts it at a remote location (Hosted PBX). The service is delivered to your premises through the internet via ADSl or leased lines.

How It Works

Hosted PBX systems all run on IP networks, meaning that they use the same circuitry and wiring as your company’s data network or LAN. They pass information back and forth via the same mechanisms as any office network or the Internet itself.

With a hosted PBX or VoIP system, your company will typically be provided with a special router or switch that attaches to the network and is then connected to the outside world. This switch or router communicates directly with the hosting service that provides the hosted PBX. Sometimes this connection is made over the public Internet (but using secure protocols), and other services that provide a dedicated connection that operates just like the Internet. However, this connection is private and restricted to provide better bandwidth, security and service levels.

When a call is made, the phone connects to the IP network, then gets switched out to the remote hosted service, which establishes what number is being called and creates a connection either via VoIP protocols across IP networks or via the regular phone system. The remote service can also create other connections, interact with the call in other ways and, in general, provide enhanced services.

The advantages of this technique are that it is easy for the service provider to upgrade the system, there’s very little local infrastructure needed at your office location and it provides good flexibility especially across multiple locations. The disadvantages are that your company loses some control, hardware is still required and your telephony is reliant on your broadband or lease line connection.

In specific circumstances Hosted can offer a viable alternative to a traditional system. Ocean Telecom can provide both hosted and traditional telephony solutions and are able to advise just what type of solution would suit your business.
