VoIP System Telephones Voice over IP (VoIP)
■
VoIP system telephone’s audio signals are generated by the telephone itself. DTMF dial tones and Music
on Hold are produced by the Media Gateway function.
■
A VoIP system telephone can also be operated without a permanent connection to the communications
system, for example via an on-demand RAS connection.
■
Signalling data for call control, call data during three-way conferences, connections to conventional ter-
minals and external connections is exchanged between the VoIP system telephone and the communica-
tions system. During a call between two VoIP system telephones, call data is exchanged directly between
the two VoIP system telephones.
■
During the device’s start procedure, the IP address is configured and the device software is requested via
the DHCP and TFTP network protocols.
VoIP System Telephone Configuration
The VoIP system telephones Comfort Pro P 300 IP and Comfort Pro P 500 IP obtain the required IP address
configuration and operating software via the DHCP, BOOTP and TFTP IP protocols. After the power supply is
assured, the device’s internal boot loader is started which controls the further start procedure.
Standard operating procedure is to contact the Comfort Pro S’s DHCP server so that the start procedure can
be concluded without problems. To register a new VoIP system telephone, proceed as follows:
1. Temporarily remove the VoIP system telephone’s ethernet connection. Switch on the VoIP system tele-
phone’s power supply. Note the MAC address shown in the display, for instance
“MAC: 00:30:42:00:00:00”. Switch off the power supply.
2. In the Configurator , open the PBX Configuration: Devices: VoIP Phones page. Click on the New button.
3. Select the VoIP system telephone’s Type and enter the previously noted MAC address. Assign a Name
and Phone No. Confirm with Apply .
4. Connect the ethernet connection with the VoIP system telephone’s RJ45 connector. Switch on the power
supply. Verify the correct start procedure on the display.
