Ambience Listening (Al); Cancelling A Call; Using In-Call Features - Motorola TETRA MTP850 Feature User Manual

Ambience Listening (AL)

This feature, if enabled by your Service Provider, allows a
console operator (or dispatcher) to establish a special call
with a specific terminal to monitor voice activity in the local
vicinity. The call is setup without any indication to the affected
terminal, and any lower priority ongoing voice call or packet
data transfer may be pre-empted.
After accepting the call, the terminal transmits in a half-
duplex Private Call without any action from or indication to
the user. The Ambience Listening call shall automatically end
when the user initiates any voice call and uses the terminal
normally.

Service Provider, the call number will be forwarded to the
missed call list.
• Press Reject soft key (displayed in an incoming full-duplex
call). The call number will be forwarded to the missed call
list.
