Embodiments of the invention provide methods and apparatus to allow a subscriber to enter a pre-specified digit sequence using the phone terminal's keypad to induce a special data collection mode for the impaired call. The digit sequence is handled in a special manner to avoid inadvertent selection of options in an Interactive Voice Response (IVR) system into which the subscriber may be dialed, or inadvertent triggering of network-based supplementary call services. In a described method for troubleshooting a telecommunication network, a pre-specified sequence of digits is entered using a keypad on an access device (510); the pre-specified sequence of digits is recognized as a troubleshooting digit sequence (520); a call troubleshooting mode is entered and optionally signaled to the network or local subscriber (530); call characteristics are captured (540); and the call troubleshooting mode is ended when the subscriber hangs up the phone and all troubleshooting data have been collected. |
