1073-70 Push-to-Mute (PTM) Specialty Handset for Avaya T7000/M3900/i2000

The 1073-70 is a push-to-mute (PTM) specialty handset for Avaya (heritage Nortel) T7000/M3900/i2000 series telephones. Using original manufacture’s equipment, the handset’s talk button assists to control background noise and privacy. The ergonomic design eases fatigue and provides maximum comfort.

The 1073-70 PTM specialty handset allows for periodic user-controlled muting of transmit speech and background noise during a call. The handset works by disabling the handset microphone when the mute button is pressed and restoring normal operation when the button is released. In doing so, the PTM handset prevents background noise and conversations from being heard at the far end (in between speaking).

Common application environments include:

  • Financial trading
  • Banks
  • Dispatch
  • Conference call participants
  • Military
  • Emergency services


Algo specialty handsets meet stringent electrostatic discharge (ESD) requirements.
