Professionally recorded messages are the prefect addition to any 1300 number set-up. Use one or a combination of recordings to boost your business image and make a great first impression.
You will most likely run into the typical Stalingrad-esque repeating messages that state how important your call is to the business. It is only slightly less annoying to have some form of default music that plays on a loop, and gives you the virtual experience of being stuck in an elevator, listening to muzak ad infinitum.

This plays immediately after the initial greeting message. If all agents continue to remain busy, the caller will continue to hear the On Hold Music, which can be either music or a message. Click Create Call Queue or click Edit (pencil icon) to the right of the queue you wish to select. Select Change under Hold Music. Enter the Name and the Phone Number or Extension you wish to record your initial greeting on. Click Call Now and follow the instructions.
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.
