Auto-answer
Factory Setting
: Auto-answer feature enabled
The Auto-answer feature enables or disables the automatic answering of incoming calls. This allows
TMA to monitor the health of the telephone via polling when SMART operation is enabled. The
telephone automatically answers the call and attempts to communicate with TMA when the auto-answer
feature is enabled. The telephone automatically transitions to a standard two-way communication if the
caller is not TMA.
