The Importance of a High Quality VoIP Conference Phones
Conference phones face a unique set of challenges that are different from mainstream phone technology. Regular phones are not designed for people talking several feet away from the microphone in rooms with an echo. The technologies used in advanced conference call systems have developed well ahead of the audio technology used in the mainstream mobile and telecom industry. The best conference phones today provide HD voice and use specialized high quality microphones. They can handle echo cancellation, noise reduction, and full duplex, resulting in clear audio from conference phone speakers.
A well-designed conference phone system will improve productivity and the quality of decision making. Participants can focus on the meeting and will not be distracted by struggling to hear what is said. This will minimize the risk of misunderstandings. During important meetings with customers, it is easier to detect subtle cues or changes in tone of voice if the audio quality is excellent.
A hundred conference calls lasting an hour each with four of your staff will cost more than $10k (if they make $60k/year). The cost of good VoIP conference phones is minor compared to the salary costs of time spent in meetings.
Different Types of Conference Phones
There are three types of conference phones: regular speakerphones, standalone conference phones, and installed systems throughout the room. The units can either use traditional analog voice or be VoIP conference phones.
Traditional speakerphones are basically desktop telephones with an incorporated speaker. They usually have no echo cancellation and only one microphone. They are designed for a single user sitting directly in front of the phone who sometimes uses it for hands-free calls. Speakerphones are not built for group discussions, and if several people sit around a speakerphone, the sound quality from the conference phone speakers is often very poor.
A conference phone is a single unit designed to operate in an open-air environment. It is a standalone device but can be supported by extension microphones. They are as easy to use as regular phones and are built to cover an entire room and all the people in it. Conference phones incorporate echo cancellation and noise reduction together with other advanced signal processing technologies for reproducing clear sound. Wireless conference phones are easier to move around but must be recharged. The market has developed enormously in the last 15 years and there are many models which are suited to different needs.
An installed conference system is built in to the room. There are a number of microphones and speakers throughout the room and some of them can be moved to accommodate different situations. Each component is controlled by a very sophisticated system that adjusts speaker outputs, the microphone gain levels, as well as the other variables required to maximize audio quality.
The installed system’s advanced signal processing can eliminate problems that often occur in a larger room. For example, loudspeaker zones, feedback, multiple echo, and other difficult noise problems experienced by conference phone speakers. These systems are often integrated with video conferencing equipment and the installation is usually done by a system integrator or A/V consultant.
Finding the Perfect System for your Conference Room
The optimal type of conference system will depend on the size and layout of the conference room. When selecting a conference phone, a lot can be achieved by improving the acoustics in the room before installation. Large windows or glass walls generate more echo while carpeting, acoustical ceilings, curtains or wall hangings will improve the acoustics.
Small Conference Room
In a small room, which seats up to four people, the size forces the participants to sit close to the conference unit. This provides an optimal conferencing experience. If a regular office is used, furniture and clutter will often improve the acoustics in the room. Conference phones designed for small rooms usually provide 5-7 feet coverage.

Traditional Conference Room
A mid-size conference room which seats between 6 and 12 people is more challenging than a small room. Participants are further away from the microphones, which makes echo and noise more problematic. If you're in need of a medium-ranging solution, make sure it has the microphone and audio features to manage a larger setup.

A boardroom is often designed more for looks than for acoustics, which can make using a conference phone setup difficult. That is, if you don't have the right one. There are installed systems that will get the job done, but some tabletop conference phones will work, if they have the right features and audio quality.

Conference Phone Features
Here are most important features to look for when selecting a conference system:
- Microphone: The quality and pickup range of the microphones is particularly important. Directional microphones will discard noise and echo coming from behind them while cheaper omnidirectional microphones will pick up noise from every direction.
- Noise reduction: Advanced signal processing for suppressing pickup of unwanted sounds is crucial.
- Full duplex sound: Full-duplex is another important feature. It will enable the participants to speak at the same time without cutting off one another. This ensures that the conversation can flow naturally without interruptions.
