Device Properties
The VoIP-enabled versions of the system telephones Comfort Pro P 300 IP and Comfort Pro P 500 IP offer the
same features as the corresponding system telephones. Using VoIP system telephones is therefore not much
different from using standard system telephones. The following differences exist:
■
Two RJ45 connector ports are available for ethernet connection. The ports are connected to one another
via the telephone’s internal switch. The switch supports 10 Mbit/s or 100 Mbit/s full-duplex with priority
given to VoIP data transmission.
LAN Port : Allows the telephone to connected to the LAN. Use a non cross-over RJ45 patch cable to
connect to a Hub or Switch.
PC Port : Allows the telephone to be connected to a workstation computer. Use a non cross-over RJ45
patch cable to connect to the PC’s network port.
■
The VoIP system telephone’s power supply is provided by an extra plug-in power supply. It is also possible
to provide a power feed via PoE (“Power over Ethernet”). PoE requires special devices for power feeds, as
well as a completely wired RJ45 connection line.
■
You can also connect a standard headset via RJ45 sockets (DHSG standard) to VoIP system telephones.
■
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.
