Installation
• Internet (VoIP accounts with one or more VoIP phone numbers similar to the PMTP
connection on ISDN and VoIP accounts with an extensions block similar to the PBX
connection under ISDN, based on the SIP-DDI feature (also known as SIP trunking))
• COMfortel 1400 IP/2600 IP/3600 IP system telephones
• COMfortel 3200/3500 system telephones (firmware version 2.6E or later)
• IP DECT single- and multicell servers COMfortel WS-400 IP and COMfortel WS-650 IP
for COMfortel M-100, COMfortel M-200/210 and COMfortel M-300/310 DECT handsets.
• Standard VoIP telephone (SIP), e. g. COMfortel 1200 IP
• Softphones (SIP)
• IP switch relays (e.g. NETIO 230B, WebRelay (identical to Keil), Energenie EG-PM2-
Lan, Philips hue)
• IP door terminals (e.g. Telecom Behnke Serie 20 IP, Baudisch SIP door terminal Maxi,
TCS FBI 6101, ELCOM LBM-300)
Requirements:
• For Internet access: Broadband Internet connection (e. g. DSL router, TV cable router)
• Existing network (LAN) or single switch (for VoIP terminals) with a data transmission rate
of 100 Mbit/s
Note: For VoIP data communication in combination with the transmission of limited
amounts 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 amounts of data (e. g. downloads), we recommend upgrading to
a data transmission rate of 100 Mbps. For this purpose, replace not only all of the
active network components (e. g. switch and router), but also all of the 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).
Note: When using a switch with PoE function, a separate power supply (e. g. via a
power plug) is not required for connected VoIP telephones, always provided 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.
