Notes: For VoIP data communication in combination with the transmission of limited
amount of data, a data transmission rate in the LAN of 10 Mbps is sufficient under certain
circumstances. For VoIP data communication in combination with the transmission of large
amount of data (e. g. downloads), we recommend upgrading to a data transmission rate of
100 Mbps. For this purpose, replace not only all active network components (e. g. switch
and router), but also all passive network components (e. g. cables and wall sockets). For
a reliable support of 100 Mbps, you need cables and wall sockets of at least Category 5
(CAT 5).
When using a switch with PoE function, a separate power supply (e. g. via a power plug)
is not required for connected VoIP phones, always provided that they support PoE.
• For the use of DiffServ for prioritising language packages: DiffServ support of all active
network components available and enabled
• NAT traversal should be carried out either by the PBX or by a well-functioning SIP-aware
router
Note: If the router is not SIP aware, several of the ports on the router necessary for VoIP
data communication must be enabled (RTP port and SIP UDP ports) (port forwarding). A
list of the ports used in the PBX can be found in the Configuration Manager of the PBX
under Overviews > Ports.
Caution: Opening a port on the NAT router is a security risk.
•Take additional protection measures.
Important: If you want to integrate the PBX into an existing network, contact the
responsible system administrator. Making changes to an existing network can cause
considerable malfunctions.
Analogue Terminals at the Internal Analogue Port
Connection possibilities:
• Analogue phones
• Analogue fax devices
• Analogue answering machine
• Modems
• a/b audioboxes
• a/b door terminals (e.g. TFS-Dialog
200/300/400, TFS-Universal plus, TSA
a/b)
For direct connection of a terminal to an
existing RJ-45 socket, you may need a
commercially-available adapter.
If the terminal has a greater distance to
the PBX, then cable and wall sockets
