I feel that the below mentioned example is wrong.. This was given in one of the famous website.

The point is, user makes 30 calls in an hr.. so mean holding time is 2 mins on avg. then how can each call can be held on an avg of 5 min in the below example ? Am I wrong plz clarify ???

For example, if a group of user made 30 calls in one hour, and each call had an average call duration of 5 minutes, then the number of Erlangs this represents is worked out as follows:

Minutes of traffic in the hour = number of calls x duration
Minutes of traffic in the hour = 30 x 5
Minutes of traffic in the hour = 150
Hours of traffic in the hour = 150 / 60
Hours of traffic in the hour = 2.5
Traffic figure = 2.5 Erlangs
