When you call a group, putting a * in front of the group's extension number turns the call into a page call.
Whilst you cannot hear the users being paged, they can answer the page call if they want. That turns the page call into a normal call between just you and the answering user.
1.The method and type of page depends on the type of group called:
•Calling Group Page: Dial *7 and the group number 1 to 4.
All available group members who have phones that support auto-answer, hear a single beep and can then hear you.
•Hunt Group Page: Dial *77 and the group number 1 to 6.
The first-available extension who has auto-answer after the last rung member hears a single beep and can then hear you.
