Modern phones have evolved into small computers (with software). Skilled attackers can reprogram these phones to eavesdrop on conversations even when the phone is on-hook by activating the microphone on the handset.
Recognizing these threats, the NTSWG, formerly known as the Telecommunications Security Group (TSG), recommends push-to-talk handsets in all secure environments and theyre required in secure government facilities.
Push-To-Talk Handsets can also be used to improve communications in extremely noisy environments. Disabling the transmit circuit removes the background noise from the sidetone making the other party easier to hear. If background noise is your problem, our noise-cancelling handsets are extremely effective, and dont require the user to learn a new way to use the phone.
Compatible with Cisco 7811, 7821, 7841, 7861, 8811, 8841, 8845, 8851, 8861, 8865 and DX600 Series phones.
Physically breaking the circuit ensures the microphone cant transmit unless the button is pressed. This increases the difficulty of an eavesdropping attack since rogue software or firmware patches cant change the physical circuit.
We stock handsets for over 1,500 phone models including handsets compatible with Cisco, Polycom, Avaya VoIP phones. If we dont stock the handset shells for your phone, we can usually modify the existing handsets to be Push-To-Talk for most phones!
