Fax Machine / Answer Machine
Step 1: TwinTalk delays ringing
When you are using TwinTalk on your line your phones, faxes and answer machines will ring slightly later than they would if TwinTalk is not connected. During this delay TwinTalk is analysing the incoming ringing pattern, which is based upon the number your caller has dialed, before it decides whether to connect the attached phone, fax or answer machine to the ringing signal (or not). When your callers phone you they will hear a couple of bursts of ringing before your phone starts to ring.
