maps them to the corresponding key
events as if the keys on the
IP Deskphone are pressed.

Incoming Call When there is an incoming call, the
IP Deskphone sends an alerting event
to the adapter. The adapter produces
the ring tones for the attached analog
device to indicate there is an incoming
call on the IP Deskphone.
Caller ID Information Caller ID, if available, is also sent to
the adapter. The adapter sends the
CLID to the attached analog device for
display.
