In one embodiment of the invention, either a CPRU or an RNC in a wireless local loop performs digit analysis to identify whether an emergency 911 call is in progress by setting an internal indicator. When the emergency 911 caller goes on-hook during an emergency call, the CPRU will direct a re-alert of the emergency caller should the internal indicator indicate that the call is an emergency 911 call. In an alternate embodiment, digit analysis is only performed at a CO in a telephone network coupled to the wireless local loop. When the emergency 911 caller goes on-hook during an emergency call, the wireless network places itself into a pending disconnect state, thereby allowing the CO to direct a re-alert of the emergency caller.
