The cell phone is the most quickly adopted new technology in history and, as of last year, 97% of all adults had one. Of that group, 56% owned smartphones that allowed them to talk, message, get online, and use social media with just a couple clicks. But despite the fact that more and more people are using mobile communications almost exclusively, good old fashioned — so to speak — phones still have their place, especially in work environments. But without the use of proper phone test sets that ensure electronic calibration, phones might be fuzzy, fail to connect properly, and make it difficult to have a quick conversation.

Verizon’s massive “Can you hear me now?” ad campaign was designed for mobile users who were having trouble hearing the person on the other end of the line. Though land lines, at least in the earlier days of mobile phones, were far more reliable, there can still be problems that make holding a conversation tough. Phrases like “what did you say?” and “can you repeat that?” can be highly problematic when workers need to get information quickly, and properly working phones are the best way to avoid them. So every business that depends on efficient communications should invest in phone test sets and other equipment calibration tools that help workers better hear each other.

One of the most important things that phone test sets can help with, beyond establishing clear lines of communication, is proper voicemail and caller ID features. Both are important in terms of efficient communications, and little digital problems on phones can cause them to not work properly. By working to meet the proper calibration standards, business owners and managers will give their employees the tools they need to properly communicate without wasting time or their vocal chords.

One thing that managers should consider when looking to invest in test sets is the ability to perform onsite calibration. Realistically, employees don’t want to get up from their desk and carry their phone down to an IT room or anything like that, and technicians often like doing onsite work so they can get more done. Finding sets that are able to work in a number of different settings, if not just offices, is an important process.

Businesses and workers alike are becoming increasingly dependent on mobile technology that allows them to communicate and get work done from anywhere. However, making sure that more traditional office phones work properly is still a wide task for managers who want to improve efficiency and encourage open communication.
