Call center cooperative implementation method and call center cooperative system

The invention discloses a call center cooperative implementation method and a call center cooperative system. In the method, an application server sends a cooperative call from a user terminal to a computer telephony integration server (CTIS), wherein the cooperative call carries the cooperative types and the uniform resource identifiers (URIs) of the user terminal under the condition that a session connection between the user terminal and a client terminal is not established; the CTIS acquires the URIs of the client terminal in accordance with the URIs of the user terminal under the condition that the cooperative call is allocated to the client terminal, and then returns the URIs of the client terminal to an application server; the application server determines the call type to be the cooperative call, and then sends a cooperative establishment message to a cooperative server; and the cooperative server establishes the cooperative session with the user terminal and the client terminal.
