Abstract

The invention is a method and system for remotely testing network paths diagnosing problems in establishing a communications link between a call-routing component and a target component in a telecommunications network environment. The test system permits a call to be originated at any end office from a remote location. Originating a call at a customer'"'"'s end office accurately recreates the customer'"'"'s experience. A test method accurately reveals problems with a specific communications path. The last mile of a customer'"'"'s connection can also be tested.
