Multi-line Telephone Call Recording - Choosing the Right Equiptment

Step One

How long do you need to keep your calls?

This will depend on whether you are recording for legal reasons, dispute resolution or for training. You must decide how many weeks, months or years it is necessary for you to keep calls. (For example you may decide that for dispute resolution you must keep calls for 12 months).

Step Two

How much time are you on the telephone?

To calculate this estimate the average length of most of your calls - (ie 5 minutes)

• Estimate approximately how many calls per person per day - (ie 15 calls could be typical).
• Then simply multiply average call length by no of calls (ie 5 minutes x 15 calls = 75 minutes per day per person).
• Lastly if each person spends 75 minutes per day on the telephone and you have 8 people being recording - this is 75 minutes x 8 people = 600 minutes (10 hours) per day.
• Work time per year - 240 days (after holidays). Therefore 240 days x 10 hours = 2400 hours per year

In the example given above the multi-channel recorders available on the Telephone Recorders Direct website would allow from approx 3-4 years of recording before the hard disk would be full and start to overwrite early recordings.
