Parameter
3 Way Conference
Notes for MP-202C when three-way conferencing is enabled and two lines are enabled:
When both phone lines are active (off hook or ringing), a user can't place a call on hold. If a call is
•
placed on hold, a busy tone is played.
When there are two active calls on one line(*), the other line is unavailable (i.e., a busy tone is
•
played on the other phone). Any incoming call to the second line is rejected.
When both lines are in a call, a call waiting for either line is rejected.
•
No confirmation tone is played after a successful call transfer in "flash + digits" mode.
•
* A two active call scenario starts when a user places a call on hold and hears the dial tone.

signal to the phone to indicate that a message is waiting. If the telephone
connected to MP-20x supports this feature, an MWI 'envelope icon' is
displayed.
