Telephone Reference
4622SW IP telephone
The 4622SW IP telephone is similar to the 4620, but with a backlit grayscale display. The
4622SW also supports Unicode. The 4622SW does not provide support for the IR interface, nor
for a handset or a physical switch-hook. The 4622SW does, however, provide support for a
one-way speakerphone, as well as two headset jacks, an advantage in a call center
environment.
4624 IP telephone
The 4624 IP telephone is a multi-appearance digital telephone with 24 call appearance/feature
buttons. With the 4624 telephone the end-user can access 12 features with the softkeys and
display control buttons. These 12 features can be used in addition to the features you assign to
the call appearance/feature buttons.
4625SW IP telephone
The 4625SW IP telephone is similar to the 4620, but with a backlit ¼ VGA 256 color display and
a slightly different stand. The 4625SW does not support the IR interface or multibyte languages.
The 4625SW otherwise supports all the applications and options supported on the 4620.
4690 IP telephone
The Avaya 4690 IP Speakerphone provides the convenience and productivity benefits inherent
in a purpose-built hands-free conference phone. It also delivers the extensive set of Avaya
Communication Manager features directly to the conference room. It offers many of the same
features as other Avaya speakerphones (360 degree coverage, two optional extended
microphones for expanded coverage, full-duplex operation) and adds to them some additional
capabilities. These include downloadable software upgrades and simplified wiring to IP network
via Ethernet LAN connectivity.
