Abstract
A method of administering an emergency call service in a public switched telephone network (PSTN) (60) includes: receiving a call at a switching facility (70) from an end user terminal (EUT) (52) served by the facility (70), the facility (70) providing the EUT (52) access to a telephone service feature; disabling the telephone service feature for the EUT (52) in response to the facility (70) recognizing the received call as an emergency call; routing the emergency call to a public safety answering point (PSAP) (80) serving a geographic region in which the EUT (52) is located; and, providing a call taker (84) at the PSAP (80) control over the telephone service feature, such that the call taker (84) can selectively enable the telephone service feature.
