Abstract
The present invention includes an aspect directed to in-band voice capabilities with security signaling. For sessions that do not involve voice, the signaling data can be sent to the alarm communication center using a data channel, without using a voice channel. In other aspects, the protocol used to transmit alarm events from the alarm device to the alarm communication center resembles industry-standard alarm format, but differs in specific ways that recognize both advantages and disadvantages of the cellular medium. In yet other aspects, the invention may use a timeout in order to ensure orderly resource management in the case of a communication failure.
