Methods for accurate transmission of ELIN/callback number from an emergency caller calling from behind a PBX/MLTS include prioritizing the emergency call, assigning a port equipment number to each device/trunk of the PBX/MLTS and associating ports/devices with ELINs and callback numbers. The apparatus of the invention detects an emergency number, assigns the call priority, and uses the port/device number to determine the ELIN/callback number and properly transmit the ELIN/callback number.

Priority based methods and apparatus for transmitting accurate emergency location identification numbers (ELINs) from behind a multi-line telephone system (MLTS)

A telecommunications system provides &ldquo;feature forwarding&rdquo; between a fixed telephone unit (such as a desktop wired telephone) and a portable telephone unit (such as a cellular telephone) that are assigned to the same prime telephone number. Thus, only one of the two phones in the telephone pair is accessible (e.g., is forwarded ring signals) at any one time. In one embodiment, the system monitors changes in state regarding whether or not the wireless telephone is in a power recharging state. When the wireless telephone is connected to a power recharger, the wired telephone is designated as the current exclusive telephone to which service features are to be applied. On the other hand, when the wireless telephone is removed from the power recharging state, the common user information necessary for seamlessly implementing common features is reallocated to providing service to the wireless telephone. The common features may include a last number redial feature, a saved number redial feature, and/or features related to accessing voice mail messages.

A telecommunications server ( ) includes a timed recall request unit ( ) coupled to a timer ( ). The timed recall request unit ( ) interfaces to the call park service ( ) and/or the call hold service ( ). When a request for a call park or call hold is made, the user is given the option of electing timed recall or no recall. If a timed recall is desired, the timed recall request unit ( ) is accessed to permit the user to either accept a default length of time or to input a desired length of time. If the user manually retrieves the held or parked call prior to expiration of the timer, the timer ( ) is reset.
