The Elvox Model 8877 is a new elegantly styled handset based on the rock solid 875 series. Each unit is equipped with a handset with speaker and electret microphone providing crisp clear audio. Tone ring signal is provided by integral speaker. Quick, easy, wire capture terminal block makes installation very simple. The 8877 has a standard hookswitch. The 8873 has a conversation privacy. The phone is activated only when called. Other residents cannot listen in on conversations and just as importantly, off hook phones have no impact on the system.
