3.2 Telephone Features C
Conditions
• The default setting for Call Waiting is “disabled”.
• When Call Waiting is enabled, a Call Waiting tone is sent to the user under the
following conditions.
1) When an outside call is received,
2) When another extension executes the “Busy Station Signaling (BSS)” feature, or
3) When a doorphone call is received.
• Setting “Data Line Security” temporarily cancels this feature.
• You can change the desired Call Waiting tone for an incoming outside call and
intercom call (Tone 1 or Tone 2). As for a doorphone call, Tone 1 is used as a Call
Waiting tone (not changeable).
• If a Call Waiting tone is heard and the CO or INTERCOM indicator does not flash, this
tone indicates Call Waiting from your telephone company. In this case, see “Call
Waiting from a Central Office” or “External Feature Access”.
• If “Hold-2” or “Hold-3” is assigned in System Programming, you must dial “20” after
flashing the hookswitch.
• You cannot transfer the new call while holding the current call. If you want to do so,
first park the original call using the Call Park feature; then hang up; then take the new
call.
