The phone book

The phone book consists of:
• Organizations – companies or organizations located in the building where the door station is placed.
• Contacts – persons belonging to an organization and sometimes also a department. You assign a speed dial number to each
contact. For each contact you can assign a fallback, to whom the call is forwarded if the original contact does not answer.
• Departments – a contact can belong to a department. You create a department when you create a contact.
• Call groups – consists of several contacts or SIP addresses. You call all recipients in a call group simultaneously, and
any recipient can answer the call.
You can print a list of all the contacts in the phone book to place next to the door station.
In the phone book you can also configure the call button, to decide where the call will go when a visitor presses it.

Voice over IP (VoIP)

Voice over IP (VoIP) is a group of technologies that enables voice communication and multimedia sessions over IP networks, such as
the internet. In traditional phone calls, analog signals are sent through circuit transmissions over the Public Switched Telephone
Network (PSTN). In a VoIP call, analog signals are turned into digital signals to make it possible to send them in data packets
across local IP networks or the internet.
In the Axis product, VoIP is enabled through the Session Initiation Protocol (SIP) and Dual-Tone Multi-Frequency (DTMF) signaling.
Example
When you press the call button on an Axis door station, a call is initiated to one or more predefined recipients. When a recipient
replies, a call is established. The voice and video is transferred through VoIP technologies.
