The GLV has a Group Listen (GL) feature. According to this feature, user can
listen on Handset / Headset and speaker. There are two types of Group
Listen, Handset Group Listen and Headset Group Listen. In Handset GL,
user can listen on both Handset speaker and Hands free speaker and talk on
Handset mic and in Headset GL; user can listen on both Headset speaker
and Hands free speaker and talk on Headset mic.
This feature is initiated when user switches between the interfaces. For e.g.,
if user is currently in handset and presses the speaker button on keypad,
the soft key on LCD shows, “Talk”, ‘Monitor” or “Cancel”. The “Talk” soft key
will switch the interface from handset to speaker. The “Monitor” option will

option is selected by the phone.
