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 line rental on numerous phone lines, and call charges are less expensive than landlines, especially overseas. Phone numbers are independent of physical phone lines and can move with the business. Remote users can have an extension on the company phone system from anywhere with a reliable Internet connection.

VoIP planning to acheive good performance

Quality of service

A well-designed business telephone system will ensure the best performance out of VoIP. 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. Planning available bandwidth carefully will give an excellent quality 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 numbers requires planning to minimise downtime. Testing is essential with VoIP to ensure the system performs according to the design.

The VoIP market is competitive and price-driven, resulting in too many providers chasing too little business. 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.

Professional VoIP design and installation serviceBusiness Telephone System design and support

Many VoIP phone system providers sell their products to customers without considering the implications to the customer’s business. As Telephony, Internet connections, email and general networking become more integrated; planning becomes even more critical.

Once a customer chooses a VoIP telephone system, will plan how to integrate it into the customer’s network to get the best out of it and to ensure no unintended effects on the existing systems.

Aspects of the design include:-

  • Ensuring existing internal systems that are available to the Internet still work correctly. This might include web servers, email systems, digital video recorders and file and print services.
  • If the existing system has multiple Internet connections, how will this be best used to make the new system fault-tolerant
  • Integrating existing VoIP investment into the new system where possible.
  • Planning to resolve problems when they occur.

Systems bought from sellers who don’t even visit the customer and who send the phones and expect the customer to self-install are unlikely to enhance the business. The real value of any new system is how it is programmed to work for the business, and the business gets the best out of it.
