4.4. IP Door Station's Speaker Output Switching Control
(only when the N-8640DS/8650DS is used)
The audio output destination of the N-8640DS/8650DS IP door station engaged in conversations with its
telephone can be switched to either the internal speaker or the speaker connected to the external speaker
terminal by the telephone's dial operation.
The switched audio output destination reverts to the speaker designated on the N-8000 Setting Software when
the conversations terminate or when interrupted by paging with higher priority.
Notes
• If the called IP door station does not have this function, an error tone sounds at the telephone that made a dial
operation, and the state returns to the conversation mode.
• The internal and external speakers cannot be used simultaneously.
