Do Not Disturb
With the Do Not Disturb(DND) feature enabled, an extension can make outbound phone calls but
inbound calls to the extension cannot be made.
If an extension user of the CooVox IPPBX system dials *74 from their phone, the system will play a
beep sound to indicate DND has been activated.
To disable DND, simply dial *074, another beep sound will play and DND has been deactivated.

the call conversation in real‐time.
