Internet telephony or Voice over IP (VoIP) can be defined as the transfer of
telephone calls over your Internet connection.
With your SpeedTouch™ you can make Internet and regular telephone calls using
traditional analogue phones, connected to your SpeedTouch™.
As VoIP signalling protocol your SpeedTouch™ uses the Session Initiation
Protocol (SIP), defined in RFC 3261.
(
The voice service on your SpeedTouch™ provides additional lines without the need
for additional copper pairs. The additional lines allow you to make and receive
several internal and external Internet calls simultaneously.
You can also connect a fax machine to your SpeedTouch™ in order to send and
receive faxes over your Internet connection or over the traditional phone line.
The following SIP configuration parameters are provided by your ISP:
Uniform Resource Identifier
User name
Password
IP address and port number (usually 5060) of the provider's registrar
IP address and port number (usually 5060) of the provider's SIP proxy server
The SIP Uniform Resource Identifier (URI) is a unique name used to identify and
locate your telephone. The SIP URI can have a numerical format or the format
user@host.
Examples:
3443614
username@hostname.org
username@192.168.10.1
3443614@hostname.org
If your provider gives you an URI in the format containing an '@', your
service provider will tell you whether the '@' can be formed on your phone
by dialing a '1', '*', or '#'.
