Call Treatment.
Each toll-free number used to provide services to end-users on the IXC-10 Canvas Platform, is known as a DNIS. The 10-digit "dialed" number provides the switch with specific instructions on how to perform its' functions for that particular call.
For instance, a telephone company may have five different toll-free numbers, each for different resellers, or branded customers, and may wish to run different recordings and/or messages for each of their resellers.
This is accomplished thru a system known as "DNIS-scripting", where upon the toll-free number dialed (DNIS) identifies the particular function, or script, that will be utilized for that call.
An example - a customer dials 1-888-888-4618, and reaches Allcom's calling card platform, which is on the same platform as the 1-800-800-8313 bypass product for Allcom; it may also be the same platform as the Pin Pay Go platform.
The switch recognizes the difference between the different toll-free numbers, and applies treatment accordingly. Treatment is the term used to describe the way that the switch provides services, based upon the DNIS of the numeber.
