IP Telephones (Voice over IP) 3. IP Telephones (Voice over IP) VoIP stands for "Voice over IP" and refers to the transmission of voice data via the Internet Protocol (IP). VoIP enables companies to use existing company data lines for telephoning without having to lay new telephone lines. To be able to use this technology however, suitable devices to support it are necessary. The following IP system telephones are suitable, e. g. Aastra 6773ip/ OpenPhone 73 IP and Aastra 6775ip/OpenPhone 75 IP. These telephones offer the same range of functions that the Aastra 6773/OpenPhone 73 and Aastra 6775/ OpenPhone 75 standard system telephones offer and are operated in exactly the same way. The number of keys and their functions and the displays are the same for both the standard and the IP system telephones. Key extensions can also be connected to IP system telephones (see also the chapter Key extensions starting on page 32). Note: Your system administrator will configure your IP system telephone for you and put it into operation. Contact the system administrator if you have any questions, if you would like more information, or if you need any help. If your system administrator has configured an IP system telephone for you, the following information will be of interest to you: ■ During some connections you may experience short breaks or hear an echo. This depends on the transmission quality of the line and is not due to your telephone functioning improperly. ■ If your telephone is being connected to the line or the connection is interrupted (e. g. if the company network breaks down), the required terminal software will be loaded when you reboot the telephone. This happens automatically and may take about 1 minute. The telephone is ready for use when the time and the labels of the configured call and feature keys are shown on the display. You can then use the telephone as per usual. ■ When telephoning via connected headset, it is advisable to wait a second after accepting an incoming call before you begin to speak. This brief time interval is necessary to allow the VoIP connection to be established between yourself and the caller. 67

IP Telephones (Voice over IP)
VoIP stands for “Voice over IP” and refers to the transmission of voice data via the
Internet Protocol (IP). VoIP enables companies to use existing company data lines
for telephoning without having to lay new telephone lines. To be able to use this
technology however, suitable devices to support it are necessary.
The following IP system telephones are suitable, e. g. Aastra 6773ip/
OpenPhone 73 IP and Aastra 6775ip/OpenPhone 75 IP. These telephones offer the
same range of functions that the Aastra 6773/OpenPhone 73 and Aastra 6775/
OpenPhone 75 standard system telephones offer and are operated in exactly the
same way. The number of keys and their functions and the displays are the same
for both the standard and the IP system telephones. Key extensions can also be
connected to IP system telephones (see also the chapter
Key extensions
starting on
page 32).
Note:
Your system administrator will configure your IP sys-
tem telephone for you and put it into operation. Contact the
system administrator if you have any questions, if you would
like more information, or if you need any help.
If your system administrator has configured an IP system telephone for you, the
following information will be of interest to you:
During some connections you may experience short breaks or hear an echo.
This depends on the transmission quality of the line and is not due to your tele-
phone functioning improperly.
If your telephone is being connected to the line or the connection is inter-
rupted (e. g. if the company network breaks down), the required terminal
software will be loaded when you reboot the telephone. This happens auto-
matically and may take about 1 minute. The telephone is ready for use when
the time and the labels of the configured call and feature keys are shown on
the display. You can then use the telephone as per usual.
When telephoning via connected headset, it is advisable to wait a second after
accepting an incoming call before you begin to speak. This brief time interval is
necessary to allow the VoIP connection to be established between yourself and
the caller.
