1 x TIM Enterprise 700 license will easily allow you to log all fifty sites. There is no site license charge as TIM Enterprise allows you to log an unlimited number of sites in a single central license. We would need to look at the network infrastructure you have in place to identify the best way to transfer call data from the remote sites to the main site for processing.

TIM Enterprise is definitely the product required here are there are no limits to the number of sites that you can log.

Managers of individual sites/groups/teams can have their own unique login that will restrict them to their own specific areas of interest. You will also be able to set up reporting collection groups for teams that span multiple sites.

There is no limit to the number of concurrent users access the system.
