If I know the probability of calls delay (% of call delay) then how to get the average delay of all calls (sec). Thank you very much in advance Jimmy. 17th January 2000 at 17:07 #32503 Lester BromleyGuest Average Delay is calculated by: W = ErlangC(m,a)/(m * u * (1 – p)) where: m = number of agents a = traffic intensity (in Erlangs) u = departure rate p = agent utilisation. 15th July 2017 at 19:21 #32504 masoudGuest tnx Author Posts Viewing 3 posts - 1 through 3 (of 3 total) The forum ‘Telecom Design’ is closed to new topics and replies.
