[Asterisk-Dev] Call center business

[izo]

Hi All,
We can see on this list lots of origination and termination offers. So
you can see and compare prices and estimate income on that business
etc.

What about call centers ? Does anyone have real world experience ?
Anybody running a call center ? What are the rates for inbound and
outbound services ? What are profit margins ?
And do you have any advices for new starters in that field.
