Step 5: Head-to-head dedicated toll-free testing

Head-to-head testing on dedicated toll-free numbers is less painful than intrusive testing on a dedicated circuit. The process doesn't take down your dedicated circuit or affect your other service in any way. Your carrier can set up a test toll-free number in order to view and manipulate the DNIS stream, as well as to identify the responses from your hardware. After you get to the point of head-to-head testing on a dedicated toll-free number, your issue is as good as fixed.

Tip Having your hardware vendor on-site or available during the head-to-head testing with your carrier can expedite the resolution. Your carrier can view and manipulate the call it's sending you, having someone with more experience around to identify what you are seeing can be infinitely useful.
