Configuring the system on the DECT Manager
Defining local communication ports (listen ports) for VoIP
This setting only has to be changed if the port numbers are already being used by other
subscribers on the LAN. You can then specify other fixed port numbers for the SIP and RTP port
or ranges of numbers for the SIP port.
The following communication ports are used for VoIP telephony:
u
SIP port
The communication port via which the phone receives (SIP) signalling data. The default
standard port number is set to 5060 for SIP signalling. You can use values between 5060 and
6000.
If several VoIP phones are operated on the same router with NAT, it makes sense to use
randomly selected ports. The phones must then use different ports so that the router's NAT
is only able to forward incoming calls and voice data to one (the intended) phone.

u
RTP port
Two consecutive RTP ports (consecutive port numbers) are required for each VoIP
connection. Voice data is received via one port and control data via the other. The system
uses additional ports for the base station connections (32 ports per DECT module), based on
a specified base port. Default setting for the base port: 10000.
The RTP port range calculated for the DECT modules is displayed on the
