In telecommunications, interconnection is the physical linking of a carrier’s network with equipment or facilities not belonging to that network.InterConnections refers to the process of connecting previously disparate systems together. Like connecting your CRM or sales management software with your telephone system. This is handy if you want to see a screen pop when an inbound call comes in from a customer. You can see the customer information immediately allowing you to better understand the needs of the customer.
Other examples are connecting your phone system with your Accounting system. This is helpful for automating communications calls to delinquent customers.
