The VoIP telephone adapter communicates with our regional VoIP switchboard to register across the Internet. When your telephone has been registered, you will get the dial-tone. This takes no more than a few seconds.
Once installed, the adapter works like a telephone of line. Lift the receiver, listen for the dial-tone and dial the number as usual.
When the user dials, the adapter calls our VoIP switchboard, which in turn connects with the number dialed, establishing the call.
