    Abstract: A system (Fig. 1) for assuring quality of service for Data Network Telephone calls such as Internet Protocol Network Telephony calls (180, 81, 203) has software (SW) for monitoring established DNT calls for adequate bandwidth. If the available bandwidth falls below a threshold, an alternative conventional call (118). Such as a PSTN or ISDN (100) call is made to replace the DNT call. Once the alternative call (118) is established, the original call (180, 181, 203) is ended. After the original call (180, 181, 203) is ended, tests of the DNT path continue and in some cases, if adequate DNT bandwidth becomes available, the call is switched back to DNT (180, 181, 203).
