Public Phones are phones set up without being allocated to a specific User. These phones can be located in a specific place that is used by many Users, such as a conference room.
Because Public Phones can be used by anyone, these phones cannot be added to a Group nor can they be allocated a Voicemail.
Otherwise extension and phone numbers, call forwarding, phone numbers, caller ID, and 999 Emergency settings can all be set up for Public Phones.
To set up a Public Phone, please use this guide.
