8.10 Monitoring A Conversation Between
Two Telephones (Service Observing)
If your telephone provides the installer-programmed service observing
feature, you can monitor an on-going conversation at another telephone
in an undetected manner. You can use this feature on-hook or off-hook.
You may also make a SOHVA call to a station you are actively
monitoring, enabling you to assist the station user while listening to the
distant party. For this feature, the called station must be programmed to
be “observable,” and your telephone must have a pre-programmed
SOHVA button.
To monitor an in-progress call,
1. Press INTERCOM.
2.
Dial
# 03.
3. Dial extension number of telephone to be monitored.
4. Press SPEAKER to end monitoring.
To initiate a SOHVA while monitoring a call at
another station,
1. Press pre-programmed SOHVA button.
2. Make announcement (distant party will not hear the
announcement; party receiving SOHVA can press MUTE button
to respond to your call).
NOTE: The station you are observing may not allow a SOHVA call if
it is in speakerphone mode. However, the voice announce
block feature, if enabled at the monitored station, will not
block a SOHVA from a monitoring station.
8.11 MutingYourTelephone
By using the MUTE button, you can block transmission of your voice
to the distant party. For example, if someone comes into your office to
talk to you and you do not want to interrupt the distant party, press the
MUTE button. The MUTE button turns on when you press it and turns
off when you press it again.
To mute your telephone,
1. Press and engage MUTE (MUTE light turns on).
To return to the distant party,
1. Press and disengage MUTE (MUTE light turns off).
