Abstract
A failsafe configuration for alternative network telephony is disclosed. An indication as to whether an alternative network telephony call processing system is available to process calls from an associated piece of telephone equipment is received automatically and transparently to a user of the telephone equipment. Calls placed from the telephone equipment at a time when the alternative network telephony call processing system is available to process calls are processed via alternative network telephony. Calls placed from the telephone equipment at a time when the alternative network telephony call processing system is not available to process calls are processed via the public switched telephone network (PSTN).
