What is VoIP?

Voice over IP (VoIP) is a technology that allows the Internet to carry voice conversations. This technology has several advantages over standard telephone systems. VoIP is much cheaper as there is no need to pay the line rental on numerous phone lines. Call charges are less expensive than land lines, especially overseas. Phone numbers are not tied to physical phone lines and can move with a user. Remote users can participate in a company phone system from anywhere with a reliable Internet connection.

BT ISDN Switch Off

BT have announced their plan to phase out the Integrated Services Digital Network (ISDNwhich has been the backbone of business phone systems since 1988. The announcement is that new installations will cease in 2020 and full switch off by 2025.

ISDN subscribers still have some time before their existing systems stop working. In many cases until your current phone system reaches the end of its useful life. For any new phone systems, there is little point investing in systems with such a short life. VoIP systems are the only practical alternative and are generally better and cheaper. The one exception to this is where your Internet connection is not good enough for reliable VoIP.

Many phone system providers are using the ISDN switch off to scare people into signing up with their VoIP solution. Do not fall for this tactic as you still have time to make a planned transition to VoIP.

VoIP Disadvantages

VoIP is not without its disadvantages. Firstly compared with traditional phone systems it is relatively new and with a wide range of hardware and service providers there can be some compatibility issues. The most likely problem areas have always been voice quality and reliability. If a company had one Internet connection with several voice connections as well as email and general Internet traffic sharing, voice quality would probably vary and if the Internet connection dropped the calls would be cut off.

Getting the best performance out of VoIP requires the system to be designed correctly. This design will include, fault tolerance, a minimum of two Internet connections will maintain both VoIP and other Internet services if a line fails. Quality of Service (QoS) will prioritise VoIP traffic so that voice will not become broken or jittery if a link becomes busy. Available bandwidth must be planned carefully to give acceptable service. Last but not least is porting of numbers. It is possible to keep your terrestrial numbers and port them over to your VoIP system. Porting is not an instant process and needs to be planned with the phone company to minimise downtime. Testing is essential with VoIP to ensure the system performs according to the design.

The VoIP market is very competitive and price-driven resulting in too many providers chasing too little business and making too little profit. The inevitable result is that some VoIP providers have gone out of business or been taken over by larger ones. For this reason, don’t buy VoIP services on price alone. The service level might be the reason for the price.
