Can anyone suggest if there are any standard norms for the inbound and outound trunking ratio's required by a call center.
Or is it all dependent upon customer requirements?
I am researching this wrt to call centers in India where the bandwidth costs will rocket as the reatios go up and this becomes very relevent as the operating costs go up.

Contact Incoming Call Management Institute. They are the absolute gurus in
Call Center metrics. I have taken a few of their coarses, purchased their books
and use their software for calculating staff and trunks. There website is
Incoming.com let me know how it goes. If you need further assistance, e-mail

Good luck.

I think you should have 1.2 trunking ratio for every seat. The .2 of line is kept aside for aux calls (internal call, conferencing, hold, etc.). Hope this helps.
