I have this information and I want to make sure I have the correct info.
4,285 calls per month
Avg. 11 minutes per call
Based on 1% blockage rate &
18% Busy Hour Factor
How many circuits do I need?
– Do you have busy hour call rate?
– Erlang B or Poisson?
Otherwise, I’d say 4285/22 days/ mo = 194/ day
say 18% peak at BH = 35 BH Calls
35 * (11/60) min = 6.5 e
Using Erlang B, you need 9 trunks
Just looking over this calc. If I use erlang b calc off of this site I came up with 13 lines.
