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, how-
ever, 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 oper-
ated in exactly the same way. The number of keys and their func-
tions 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).
If your system administrator has configured an IP system tele-
phone for you, the following information will be of interest to you:
z
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.
z
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.
z
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.
