Abstract: An approach for providing retrieval of information over a packet switched network is disclosed. A client is configured to transmit a request message for information over the packet switched network. A stateless-server is configured to communicate with the client and to forward a portion of the information to the client in response to the request message, wherein the client transmits a selection message specifying whether the remaining portion of the information should be retrieved from the server. The server selectively forwards the remaining portion of the information to the client. The above approach has particular applicability to a communication system providing directory assistance services.

Abstract: An approach for processing a call from a calling party to a called party in which the called party requires operator assistance is disclosed. A bridging switch receives a call offer from the calling party and forwards the call offer to an automatic call distributor (ACD). The ACD selectively distributes the call offer to a local operator, instructing the local operator to establish the call with the called party. The local operator, such as an audio response unit (ARU), establishes the call. A remote operator collaboratively communicates with the ARU over a packet switched network to control call processing.

Abstract: Method and apparatus allow a caller to contact a called party with a collect call whether or not the called station is answered or is busy. When the caller dials a collect call access code, the call is routed to a messaging platform which collects the call information and attempts to complete the call. If there is no answer or if the called station is busy, the messaging platform retains control of the call and automatically prompts the caller to enter a name and a message to be delivered to the called party. After the name and message have been entered, the caller is given a confirmation number, if desired, which allows the caller to determine whether the called party has received the message. The messaging platform repeatedly attempts to deliver the message by calling the called party. Upon the call being answered, the messaging platform identifies the caller and prompts the called party to accept or refuse the collect message.
