VoIP Telephones VoIP Telephones VoIP stands for "Voice over IP" and refers to telephony where voice data is transmitted via Internet Protocol (IP). VoIP enables companies to use existing company data lines without having to lay new telephone lines. To be able to use this technology, however, suitable devices which 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 30). 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 (the telephone "reboots"). This happens automatically and may take some minutes. The telephone is ready for operation when the display shows the time and the internal call number. Then you may 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. 89

VoIP Telephones
VoIP stands for “Voice over IP” and refers to telephony where voice data is transmitted
via Internet Protocol (IP). VoIP enables companies to use existing company data lines
without having to lay new telephone lines. To be able to use this technology, however,
suitable devices which 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 con-
nected to IP system telephones (see also the chapter Key Extensions starting on
page 30).
If your system administrator has configured an IP system telephone for you, the fol-
lowing 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 (the telephone “reboots”). This happens automatically and may take some
minutes. The telephone is ready for operation when the display shows the time
and the internal call number. Then you may 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.
