For those still using analogue or digital phone systems, voice on ISDN circuits has a bandwidth of around 4000Hz. The audio from an analogue phone is sampled at 8000Hz, and because of the nyquist theorem, must be low-pass filtered to 4000Hz. So any frequencies in the audio beyond 4000Hz are lost. Interestingly, the human ear and mind are good at recognising human speech, so this is considered "toll-quality" voice, i.e. good enough to pay for. This is the reason why certain vocalised letters are difficult or impossible to tell apart on the phone. For example, the differences between B, P, T, C, etc. are almost entirely above 4000Hz.
In the first instance, we work closely with you to better understand the process you expect your staff to follow and can offer guidance on best practice and identify any obvious issues before we even begin. Once we start analysing your calls, we will simply listen to real customer and prospect calls and measure both the ‘process’ and ‘experience’ aspects. You can then expect to receive detailed, monthly reporting that allows you to quickly understand your current performance and identify where you need to be and how to get there, so you’ll be one step closer to achieving your business goals.

A well written script is the cornerstone of any great on hold message. It must capture the caller’s attention, so they remain engaged while navigating menu options or waiting on hold. The script that callers hear can set the tone for the rest of the conversation. It should also be in line with your goals, which can be broken down to 3 main objectives. It can be to inform the caller, promote the brand or product, or just entertain the caller. Most of all, it has to be engaging.
“Superbly written copy and extremely dry humor that was a perfect match for what could've been a dull subject. I laughed out loud at points, and when a caller starts with that reaction, it's a great way to start a conversation.” - Jim Hausfeld / On Hold Messaging Association's MARCE Awards Judge
