Configuring the phone via the Web configurator
Defining R key function for VoIP (hook flash)
You can specify the function for the R key on the web page:
¤
Settings
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" as the R function to the R key on the handsets. Prerequisite: The R key is not used for call
transfer (default setting, see above).
If you press this key during a VoIP call, the signal is sent. This requires that DTMF signalling via
SIP info messages is activated on the phone (see above).
Defining local communication ports for VoIP
The settings for the communication ports are on the web page:
¤
Settings
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.
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 default
standard port number is set to 5004 - 5020.
This setting only has to be changed if the port numbers are already being used by other
participants in the LAN. You can then specify other fixed port numbers or port number ranges
for the SIP and RTP port.
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. Use the Web configurator to
specify a port number range for the SIP and RTP port that the ports are chosen from.
Making settings for access to Internet services
You can use the following Internet services on your phone.
u
E-mail notifications
In order to use the e-mail function of your base on the handset, you have to save the address
of the incoming e-mail server and your personal access data for your mailbox in the base.
You can also specify the time interval at which your phone should check whether the
incoming e-mail server has received new e-mail messages, and specify whether
authentication on the incoming e-mail server should be carried out via a secure connection.
You can change the settings on the web page:
