"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 signal-
ling data. Specify a number between 1024 and 49152. The default port number for SIP sig-
nalling is 5060.
RTP port
Specify the local communication port that the phone should use to receive voice data. Enter
an even number between 1024 and 49152. The port number must not be the same as the
port number in the SIP port field. If you enter an odd number, the next lowest even number
will be selected automatically (e.g., if you enter 5003, then 5002 is set automatically). The
default port number for voice transmission is 10000.
ICE enabled
Choose whether or not to use ICE (Interactive Connectivity Establishment). ICE is similar to
STUN (
), a Session Initiation Protocol (SIP) method for overcoming NAT firewalls.
