3-Way-Calling

This is a service provided by some telecommunication service providers. BT

in UK offer this service. When a call is in progress on a telephone line it is

possible to send a signal via that line to the equipment at the telephone

exchange. The exchange will put the current call on ‘hold’ and provide a

dialling tone so that another outgoing call may be made. When this second

call has finished a signal to the exchange will disconnect the second call

and re-connect the first one that was put on ‘hold’.
