2.1 Calculating Disk Size Required for Recordings
The table shows how many gigabytes (GB) per day you typically use given the number of recording ports you have and the average utilization of these ports over the working day. The figures are based on the assumption that your compressed recordings will be at 16kbps (a single G.726 file) and that the utilization is averaged over an
The assumptions are:
∙Compressed Audio - G.726 16kbps per call.
∙Resulting in - 7.2MB per hour of recording.
∙Hours per day - 8 (typical single shift).
