A system and method for diagnosing and/or configuring a security device included within a secure network is disclosed. A technician mobile computing device maintains a data connection between the security device and a remote computer diagnostic workstation, where the computer workstation might send configuration commands to the security device and receives diagnostic data from the security device over the data connection. The technician mobile phone maintains the data connection by establishing a wireless data link to the security device and by encoding data onto and/or decoding data from a voice connection to a peer mobile computing device. A WiFi connection between the peer mobile computing device and the computer workstation then completes the data connection between the security device and the computer diagnostic workstation.
