Hotdesking? No problem. A cordless phone can go wherever you go, whether that means pacing up and down the office aisle, making a cup of tea or working on-site.

The best cordless phones are made by a handful of major phone hardware manufacturers, including Siemens, Panasonic and Yealink. Below we’ve provided a concise round-up of the best and most popular cordless ranges and models for business use.

What are DECT cordless phones?

DECT stands for Digital Enhanced Cordless Technology. It’s a European standard of cordless phone technology. There’s no need to know the ins and outs of the science behind it, but just know that it meant a turning point for cordless systems. It’s the reason we can experience the same call quality on cordless handsets as on traditional ones.

DECT phones have a base station that can typically support up to six cordless handsets. The base station connects to the network by either an analogue or digital phone line, and handles the radio part of the connection to and from the handsets.

Cordless phones typically have a range of 50 metres indoors and up to 300 metres in an open space, depending on the model. You can easily get a booster unit to increase this distance. They usually have a battery life of around 12 hours when in use and up to two hundred hours when on standby. The handset will automatically recharge each time it’s replaced onto its base unit cradle.

When integrated with a modern VoIP PBX phone system, some models will allow users to send SMS text messages and even access their emails as part of a broader Unified Communications framework.

How much do cordless phones cost?

Cordless office phone handsets can start from as little as £30, and can cost over £100 for the most advanced models.

The more expensive handsets will generally offer more features, longer battery life, increased range and better quality calls. The overall cost will very much depend on the number of people using the system and how many handsets they need. Small business owners or home office workers should ensure they understand the differences between available phone systems.

If you want to expand your system as the business grows, DECT cordless phone systems are easy to add to by simply purchasing additional base stations and handsets as required.
