Frequently Asked Questions

With VoIP telephony there are many questions raised by UK businesses - Our experts have provided the answers

What is the difference between VoIP and a PBX system?

A PBX (Private Branch Exchange) is often referred to as a TDM (Time Duplex Multiplexer) phone system. The traditional PBX system is typically an on-premise system which is not connected to an ISDN service rather than a data network. VoIP (Voice over Internet Protocol) is the next generation phone system technology, which means that the voice is converted into data and transferred over the data network. VoIP phone systems are commonly hosted but can be on-premise in some instances. The management of a PBX system can be more time consuming than a VoIP solution. With VoIP, it can be as simple as adding licenses and moving on, compared with PBX which often required cards or cabinets and requires an engineer onsite to physically install components.

Is there a contract with VoIP?

Full flexibility is offered with VoIP solutions. You can choose from monthly rolling contracts to 36 months depending on your requirement and budget.

What does it cost to add a phone?

Refurbished handsets are available from £50.00 one-off fee. New handsets from leading manufacturers including Cisco, Polycom, Yealink and Wildix start at £75.00 with the average handset cost at around £130.00.

Is a mobile VoIP solution available?

Yes, VoIP applications can be run on mobile devices, tablets, laptops and desktop PCs. Soft phones are commonly used in conjunction with headphones via the stereo jack port or using bluetooth.

Do I need dedicated bandwidth for a VoIP system?

VoIP users do not require dedicated bandwidth, but it is crucial that users have a good connectivity to ensure that call quality isn't compromised.
