What Are the Benefits of Cordless Office Phones?

These are the most important benefits you will get from having cordless phones in your office:

Sound Quality

When compared to mobile phones and even desk handsets, leading cordless phones were found to have superior sound quality. This can be a major advantage to work places where a number of calls are being made at the same time and volume levels can be known to rise, sometimes hindering calls being made if the voice quality isn’t clear enough.


The most obvious benefit of cordless office phones is the mobility they offer to users. We have all been on calls at one time or another where we find ourselves wanting to roam and wander to raise energy levels or keep concentration, and with cordless office phones this is easy to achieve.


The flexibility that cordless phones offer mean calls can also be taken and made wherever someone is within an office or workplace. This is particularly useful for large businesses where users may wander some distance from their desks but still need to be contacted or make calls themselves.


One of the key advantages of cordless phone systems is that they are extremely easy to expand. If you are part of a growing organization with new hires joining often it is not uncommon to quickly run out of phone handsets or for communications to stall because of a result. With cordless office phones , your system can grow quickly with new handsets and docks being added to an existing setup.

What is a DECT Phone?

There are two main types of cordless phones, analog and DECT. DECT stands for Digital Enhanced Cordless Technology, and is a term describing IP phones that are capable of delivering high-quality wireless voice communications to employees who work away from their desks and roam within a building, campus or other work environment.


ECO DECT phones incorporate an energy-saving power supply, which uses up to 60% less energy than conventional DECT cordless phones.

The handsets receive their signals from one or more base stations, but can only operate within the range of the base station. The 1.9-Ghz frequency band that DECT phone operates within minimizes interference from other every day devices, aiding sound quality and improving the range that handsets can be operated at.

The base stations also act as charging devices for the handsets, charging DECT phones quickly and allowing them to improve the length at which they can be used when they aren’t docked.

DECT handsets offer important benefits, including high security, scalability, low power consumption and long talk/standby times. Many models include productivity features such as SMS messaging, intuitive menus, graphical displays and telephony features such as hold, conferencing, and messaging.

The difference between cordless and wireless phones

Cordless IP phones connect to a base unit that functions in essentially the same way as a conventional IP desk phone. The base station is connected to a landline or VoIP service. The phone’s ability to work is determined by the operating range of the base station.

Wireless IP phones use the business wireless LAN to connect directly to a PBX (private branch exchange) or network router to access the external telephone service. These phones do not require a base unit and this gives them a more flexible operating range.

Wireless phones may also be used more commonly to refer to systems such as VoIP headsets which have advantages of their own depending on the sector your business is in.
