Chapter 4: Avaya 96X1 SIP agent
deskphones
9608, 9611G, 9621G, and 9641G are part of the multiline 9600 Series IP Deskphones. The
deskphones are signaling protocol independent with two telephony applications, Avaya Deskphone
H.323 and Avaya Deskphone SIP, that support H.323 and SIP respectively.
9621G and 9641G are touch-based deskphones with a color display. 9611G and 9608 are button-
based deskphones. 9611G has a color display while 9608 has a monochrome display. With the
9641G, 9608, and 9611G models, you can use a dual headset adapter so that two persons can
listen to calls. You can also attach more than one Button Module (BM) to these deskphone models
to extend call appearances, bridge appearances, or feature keys. For an agent, the deskphones
offer convenient features and capabilities, including a phone screen to view and manage calls, and
icons that indicate agent status, call state, feature status, queued calls, and missed calls.
