Features and Services
MCT can be activated against only one established call at a time, regardless
of the number of TRC keys defined.
The Meridian 1 is responsible for seizing the trunk to which recorders are
connected. When a recorder is involved in the call, the call is treated as a
conference call. The party on the source side is allowed to disconnect from
the call; doing so also disconnects the recorder and resets the TRC key lamp
to dark.
There is no special provision for warning tones while there is a conference
with the recording device. The trunk is seized on the basis of the SRCH
prompt in LD 16.
