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.
