Set up 1-Way Paging
Paging is used to make an announcement over the speakerphone to a phone or group of phones. The called parties will not ring, but instead answer immediately into speakerphone mode.
Note: Paging is typically one way for announcements only.
Go to PBX > Call Features > Paging and Intercom , click Add.
Set a 1-Way paging group.
Paging Extension: Use the default or specify a number for the paging group.
Group Description: Enter a name for the paging group.
Device List: Choose the group members to the Selected box.
Duplex: if you don’t select the checkbox beside Duplex, it means the 1-way audio.
Click Save and Apply.
When you dial the paging group number, the members in the group will hear the announcement.
