Moreover, 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.

It is also possible to connect a fax machine to your SpeedTouch™, enabling to send and receive faxes over your Internet connection or over the traditional phone line.

Following SIP configuration parameters are provided by your ISP: Uniform Resource Identifier (URI)

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 be in a numerical format or in 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 ‘#’.
