Enter the call quantity, the average call length (min), and the recording bitrate (kbps) into the Call Recording Storage Calculator. The calculator will evaluate the Call Recording Storage. 

Call Recording Storage Formula

The following formula is used to calculate the Call Recording Storage. 

CRS = Q * CL * 60 * BR /1000


  • CRS is the Call Recording Storage (MB)
  • Q is the call quantity 
  • Cl is the average call length (min) 
  • BR is the recording bitrate (kbps) 

How to Calculate Call Recording Storage?

The following steps outline how to calculate the Call Recording Storage.

  1. First, determine the call quantity.
  2. Next, determine the average call length (min). 
  3. Next, determine the recording bitrate (kbps). 
  4. Next, gather the formula from above = CRS = Q * CL * 60 * BR /1000.
  5. Finally, calculate the Call Recording Storage.
  6. After inserting the variables and calculating the result, check your answer with the calculator above. 

Example Problem:

Use the following variables as an example problem to test your knowledge.

call quantity = 100

average call length (min) = 3

recording bitrate (kbps) = 128

CRS = Q * CL * 60 * BR /1000 =  ?
