Re: E1

This is calculated using the Erlang formula. Free Erlang calculators are available in the internet. Use Erlang B for the calculation of necessary B-Channels (which is what you need). Callcenter calculators are using the Erlang-C formula. Here is only one of the many examples:

Erlang B: http://www.erlang.com/calculator/erlb/

Erlang C: http://www.kooltoolz.com/ccm.htm?gclid=COOX0Jq586ICFUfX5woddySqhQ

Hi Patrick,

I think he is asking about normal users not Contact Center.

Erlang calculation for Call Centers.

Erlang B to calculate IVR and trunk ports ( as you know in IPCC you are expection calls more than agents)

Erlang C to calculate the Agents.

Re: E1

Erlang "calculations" are useless in most cases.

Some users do a lot of calle and some do never calls.

The only working way is to observe real usage of an exisiting trunk.

There is also an Erlang C

There is also an Erlang C Calculator in Excel format which could help with your calculations

This also contains shrinkage calculations so will be more accurate.
