The present invention proposes a method for providing Value Added Services (VAS) to a subscriber without using prefix. The method includes intercepting a call control associated with a call from the subscriber to a recipient, at an Interceptor unit, while a voice circuit associated with the call is held at a switch, without answering the voice circuit. The subscriber calls a recipient's number without any prefix. Further, the method includes sending a message by an intelligent interactive unit to the subscriber for making an indication of a service selection by presenting a user interactive menu in the message. The separate channel is established in parallel with the voice circuit. The method further includes sending by the intelligent interactive unit, the indication of the service selection, received in an acknowledgment to the message, to the Interceptor unit. Furthermore, the method includes determining by the Interceptor unit, a service application using the indication of the service selection.
