Proxy server address
The SIP proxy is your VoIP provider's
gateway server. Enter the IP address or
the (fully-qualified) DNS name of your
SIP proxy server. Example:
myprovider.com.
Proxy server port
Enter the number of the communica-
tion port that the SIP proxy uses to send
and receive signalling data (SIP port).
Port 5060 is used by most VoIP provid-
ers.
Registrar server
Enter the (fully-qualified) DNS name or
the IP address of the registrar server.
The registrar is needed when the
phone is registered. It assigns the pub-
lic IP address/port number to your SIP
address (Username@Domain) that were
used by the phone at registration. With
most VoIP providers, the registrar
server is identical to the SIP server.
Example: reg.myprovider.com.
Registrar server port
Enter the communication port used in
the registrar. It is mainly port 5060 that
is used.
Registration refresh time
Enter the time intervals at which the
phone should repeat the registration
with the VoIP server (SIP proxy) (a
request will be sent to establish a ses-
sion). The repeat is required so that the
entry of the phone in the tables of the
SIP proxy is retained and the phone can
therefore be reached. The repeat will
be carried out for all activated VoIP
phone numbers.
The default is 180 seconds.
If you enter 0 seconds, the registration
will not be repeated periodically.

Area:
Listen ports
Specify the phone's local ports for VoIP
telephony here. The ports must not be
used by any other subscriber in the LAN.
SIP port
Specify the local communication port
that the phone should use to send and
receive signalling data. Specify a
number between 1024 and 49152. The
default port number for SIP signalling is
5060.
Note:
Ports 0 to 1023 should not be used,
because these are often used by standard
applications.
RTP port
Specify the local communication port
that the phone should use to send and
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
you enter an odd number, the even
number just below it will be set (e.g. if
you enter 5003, 5002 is set). The
default port number for voice transmis-
sion is 5004.
Note:
Ports 0 to 1023 should not be used,
because these are often used by standard
applications.

any free ports.
The use of random ports makes sense if
you want several phones to be oper-
ated on the same router with NAT. 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.
If you click on No, the phone will use
