Defining R key functions for VoIP (hook flash)
You can specify the function for the R key on the Web page:
¤
Settings Telephony
Your VoIP provider may support special performance features. To make use of these
features, your phone needs to send a specific signal (datapacket) to the SIP server.
You can assign this "signal" as the R function to the R key of the handsets. Prerequi-
site: The R key is not used for call divert (default setting, see above).
If you press this key during a VoIP call, the signal is sent. This requires that DTMF sig-
nalling 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 Telephony
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 for voice transmission.
This setting only has to be changed if the port numbers are already being used by
other subscribers 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, you have to save the address of
the POP3 server and your personal access data for your mailbox in the base.
You can save the access data for up to six e-mail accounts on your base and
assign the related incoming message lists to the individual handsets registered.
You can also specify the time interval at which your phone should check
whether the POP3 servers have received new e-mail messages and specify
whether authentication on the POP3 server should be performed via a secure
connection.
