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. Forum IPhone 525 and
Forum IPhone 535. These telephones offer the same range of functions that
the Forum Phone 525 and Forum Phone 535 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 tele-
phones (see also the chapter
Key Extensions
starting on page 31).
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 inter-
rupted (e. g. if the company network breaks down), the required terminal
software will be loaded (the telephone “reboots”). This happens automat-
ically 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.
