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 8-hour working day. Should your circumstances differ, recalculate the figures according to the hours over which your port utilization is averaged.

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).

Type of Operation

	PBX Extn	Busy - Extn	Typical Call Center	Extreme Call Center
Ports Utilization	10%	30%	70%	100%
10	0.1	0.2	0.4	0.6
20	0.1	0.3	0.8	1.2
30	0.2	0.5	1.2	1.7
40	0.2	0.6	1.6	2.3

∙Note - All figures are in GB per day.

Total requirements

Use the following table to determine the required disk capacity for your recorder.

Allow	For	Comments
10GB	System overhead and	PostgreSQL database, Java Virtual Machine, and call details
	call details database	for 5 million call records online. Buffering space for DVD
		archive, etc.
Daily Usage x	Compressed recordings.
(days required online + safety
margin)

Examples

Environment		Daily Storage	Total Storage
Typical office recording		0.2GB/day	10 + (30 x 0.2) = 16GB
∙	30 extensions in normal PBX environment	(G.726 16kbps recording)
∙	10% utilization over 8 hour day)
∙	30 days online storage
∙	1 million call records kept online
Small Informal Call Center		0.5GB/day	10 + (90 x 0.5) = 55GB
∙	30 extensions in light use	(G.726 16kbps recording)
(30% utilization over 8 hour day)
∙	90 days online storage
