Cordless DECT Telephony for VoIP

Detecting Defects and Correcting Connections

DECT, an abbreviation for Digital Enhanced Cordless Telecommunications is a standard for cordless telephony. It refers to the communication between one base station and multiple handsets and is compatible with ISDN, analog or IP telephony. Despite being a fairly old, it is still one of the most prevalent technologies to realize cordless phone systems. A single cell system is usually used for smaller companies, whereas multi cells are used to cover larger areas. Multi cells provide roaming within the company, which means that one handset’s connection can jump from DECT base to DECT base.

Advantages of DECT

DECT is especially useful for companies whose phone systems have a large area to cover. Making it possible for employees to move around freely during a call, simplifies the workflow and saves precious time. However, if the connection is not steady, it can pose a wide range of problems.
DECT has the advantage over other technologies (like wifi or Bluetooth) as it provides a high level of call stability, given that it has been installed correctly. This way employees don’t need to fear that a connection could break off while being in an important conversation with a client or colleague.

Challenges for Installing DECT

As previously mentioned, DECT is useful to cover large areas with stable phone connections. However, there are many geographical and architectural challenges to be considered. Fire doors are a classic example for causing trouble with the phone system. If an employee was to walk through a fire door while on the phone, any connection would break off. Mirrored glass windows are another known cause of trouble for DECT signals. Big, moving objects can also interrupt a connection, calling for a detailed plan in firms like care dealers that has to take into consideration that there may suddenly be a car causing attenuation of the signal.
The solution with DECT is simple: There needs to be a system of multi cells that allows the handset to log from one base station to the next, ensuring the continuation of the call. Although easy in theory, installing a multi cell system needs a certain level of skill and planning, as there are many other unique qualities to the set-up of a company’s premises. But once a well thought-out system is in place, the DECT technology is a great solution for cordless telephony in an office. It can be easily expanded by simply increasing the number of base stations, allowing it to grow with the company.

Analyzing Illumination for DECT

For small companies, a single cell DECT system is still the go-to solution for telephony. If a multi cell system is needed, the first step should be to carefully examine the premises. A coverage test is carried out with measuring kit for DECT systems. Usually this service is provided by whoever installs the system. A proper analysis of coverage and attenuation throughout the building ensures that coverage is provided everywhere.
Despite the analysis being an investment, it should be carried out with care and know-how, as the cost for base stations can easily add up. Optimizing the placement of the stations does not only save money in the long run, it also ensures the coverage throughout the company. In places with a heavy call load, several bases should be placed to increase call capacity, while places with a lower call load can be covered with a repeater.

Askozia: All Hands on DECT

A great advantage of DECT is its compatibility with ISDN, analog or VoIP. However, many providers have trouble combining the technologies seamlessly and trouble-free. AskoziaPBX supports multi cell operation for a variety of phones with all the advantages of auto-provisioning.

Auto-Provisioning with Askozia

Auto-provisioning (or auto-configuration) is simple and saves time and resources when installing one or more IP phones in a VoIP PBX. It saves users the possibly nerve-wrecking task to configure every phone manually, because the singular phone gets its data from the network. This saves a lot of time (and therefore money) for bigger installations. Additionally, updates and special configurations can be centralized, without having to configure every phone individually.
Even though this is known to be a problem for DECT telephones, Askozia offers an elegant solution for configuring DECT phones with easy-to-use auto-provisioning.
