What are Push-To-Talk (PTT) Handsets and How Do They Work?

Push To Talk HandsetPush To Talk Handset

Push-To-Talk (PTT) Handsets Arent Just for the Government.

Beyond national security, many other industries follow similar security guidelines to protect their trade secrets and sensitive client information:
  • Medical Offices
  • Trading Firms
  • Legal Offices
  • Banks
  • Corporate Board Rooms & Executive Offices
Push-To-Talk (PTT) Handsets are an essential component in secure environments.

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.

A Push-To-Talk handset physically breaks the circuit to the transmitter (microphone) unless the button in the handset is pressed.

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.
