Embodiments of the present invention address deficiencies of the art in respect to call center wait queue management and provide a novel and non-obvious method, system and computer program product for call-back reservation services in a remote call center computing environment. In an embodiment of the invention, a call-back reservation method can be provided. The method can include receiving a telephone call to a remote call center from a caller, informing the caller of a reservation options menu, calculating multiple reservation time-slots to accommodate the caller's schedule, such that the reservation time is based on caller's personal preference, assigning a call-back reservation token to the caller, disconnecting the caller from the remote call center, and providing the caller with access to a remote call center agent at the reservation time when the caller reconnects to the remote call center.

A system and method for asynchronous conversation routing and tracing that allows a client and agent to connect and reconnect to one another over a discontinuous engagement. The system and method facilitate this by allowing multiple methods of communication between the client and agent, including live communications and out-of-band communications. All communications between a client and agent are tied to a client case accessible by the agent, and the client case can include context and environmental data to further assist the agent or to route a customer service call to an appropriate agent. At any time, the client or agent can send out-of-band messages to one another to advance the customer service process, or the client or agent can seek to re-establish live communication with each other. This provides the client with a consistent point of contact not easily supportable with phone based call centers where support is single-threaded.
