We’d like to thank Jeff Adams for taking the time to review Backbone Talk, our Voice over IP (VoIP) Talk Radio Phone System for Broadcast Beat Magazine. In the review he walks through the product showing how you screen calls, make notes, place certain callers on a blacklist and put them on the air.
There is quite a bit there to see in the video review. What you might not get from watching the review is the quality of the calls. The connections between the caller and the talent determines the overall quality of sound you would hear. For example, if some one calls in from a mobile phone with little signal you will hear the degraded quality. The connection from the cell-phone to the tower would most likely be weakest link.
Old wireline phones use a narrowband speech codecs like G.711 which in general are optimized 300–3400 Hz audio. For standard phone calls Backbone Talk uses the G722 Codec. G722 provides improved speech quality due to a wider speech bandwidth of 50–7000 Hz. G.722 samples audio data at a rate of 16 kHz (using 14 bits), double that of traditional telephony interfaces like G.711. The result is superior audio quality and clarity. A difference you can certainly hear.
We will be writing more on this topic and ways that we are delivering high quality audio for our customers. Please leave your comments below on what you would like to hear from us on this topic.
