Remote wiretapping Interconnect server for CISCO IP Phones

As requested by a security company in Bahrain we developed a php server system to act as a middle agent in IP telephony network running CISCO CUCM to connect remote IP phone's microphone to a monitoring IP phone speaker in stealth mode. We used CISCO phones’ (Cisco IP Phone 7940) vulnerability(discovered on 2007) to Uniform resource identifiers (URIs) commands to connect remote phones Mic with the IT Admin’s phone using a PHP based server.
