Defining recall key functions for
VoIP (hook flash)
Your VoIP provider may support special
performance features. To make use of
these features, your phone needs to send
a specific signal (data packet) to the SIP
server. You can assign this "signal" to your
phone's recall key.
If you press the recall key during a VoIP call
the signal will be sent to the server.

Telephony
In the
Listen ports for VoIP connections
specify which local ports the telephone is
to use for VoIP telephony. 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.
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

even number will be selected automat-
ically (e.g. you enter 5003, then 5002
is set automatically). The default port
number for voice transmission is 5004.

The use of random ports makes sense
if you want several phones to be oper-

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.
