3. On the row of the number you want to edit, click Actions > Edit User Features.
Call Forwarding -- choose when calls are forwarded: always, when the line is busy, or when the line is not answered.
Business Continuity -- direct calls to a number should the user's phone not be connected to the network due to a power outage, storm, or network issue. By default, calls are forwarded to a user's voicemail when they're on a call or when they don't answer the phone.
The Push To Talk feature allows a phone to be used as an intercom to directly contact another extension.
Click the Push To Talk tab.
Change the Push To Talk toggle to "on."
To choose the connection type, do one of the following:
If an extension can only receive the radio message, select the One-Way radio button.
If an extension can receive and reply to the radio message, select the Two-Way radio button. In our example, we selected two-way.
From the Approved Users list, select whether users are approved or blocked, then click the Find and assign field to select users to add to the list of approved or blocked users. In our example, we approved users.
Click Save. To turn Push To Talk off, go back to the toggle button and click it to "off."
