The present invention is a method, system and apparatus for remote initiation of communications. In some embodiments, an initiation apparatus establishes communications with a remote device via an intermediate apparatus. The initiation apparatus is coupled to the intermediate apparatus via a packet-based network and the intermediate apparatus is coupled to the remote device via a second network. The initiation apparatus lacks direct access to the second network. The initiation apparatus verifies the integrity of the communication link with the intermediate apparatus. If the integrity of the communications link is confirmed, the initiating apparatus generates a connection initiation request that comprises information representing changed state of at least one control lead. The connection initiation request is relayed to the intermediate apparatus via the packet-based network. The intermediate apparatus extracts information representing the changed state of at least one control leads. Based on the received information, the intermediate apparatus establishes a communication session with the remote device. Upon successful establishment of the communication session, the intermediate device transmits a call set-up confirmation comprising information representing the changed state of at least one control lead to the initiation apparatus. Upon receipt of the call set-up confirmation, a two-way end-to-end communication session is established between the initiation apparatus and the remote device. The present invention further provides an apparatus that allows for generating arid relaying various requests via a packet-based network while preserving the information representing the changed state of at least one control lead.
