A system for integrating electronic location indicating systems (e.g., electronic door lock systems) with telecommunication systems (e.g., a PBX). This integrating of systems is done to improve the performance of a telecommunication feature, such as the camp-on feature. An electronic system is used to transmit a signal indicating information related to the user's location. A telecommunication system then receives the signal from the electronic system. This telecommunication system is capable of providing the telecommunication feature (e.g., the camp-on feature). The telecommunication system uses the signal from the electronic system as an input to the telecommunication feature.
