Voip Settings - Gigaset DE410 IP Pro User Manual

Configuring phone settings via the Web configurator
Warning
Do not change these values without consulting your network operator first. A higher
value does not necessarily mean a higher priority. The value determines the service class,
not the priority. The prioritisation procedure used in each case meets the requirements of
this class and is not necessarily suitable for transferring voice data.
Detailed information on the Diffserv protocol can be found in RFC 2474 and RFC 3168.

VoIP settings

On this screen you configure the ports for establishing VoIP connections.
¢
Settings Network and Connections
"Listen ports" for VoIP connections
¤
Select the ports on which your phone expects incoming VoIP connections.
Use random ports
¤
Select Yes if the phone should use any available ports for the SIP port and RTP port instead
of fixed ports.
The use of random ports is advisable if you want multiple phones to be operated on the
same router/gateway with NAT. The phones must then use different ports so that the NAT
for the router/gateway is only able to forward incoming calls and voice data to one (the
intended) phone.
¤
If you click on No, the phone uses the ports specified in SIP port and RTP port.
SIP port
Specify the local communication port that the phone should use to send and receive sig-
nalling data. Specify a number between 1024 and 49152. The default port number for SIP
signalling is 5060.
