A network transfer system for transferring a voice call and data between
two or more call centers linked by independent voice and data networks is
disclosed. The system effects the transfer of the voice call over the
voice network without requiring additional information to be transferred
with the call. A network transfer module receives a request from the
sending call center and directs the sending call center to connect the
call to a specific address in a receiving call center. The network
transfer module transfers the data to the call receptor in the receiving
call center where it is associated with the address to which the call has
been directed. The call receptor at the receiving call center assigns a
time acceptance window to each call being sent so that data association
with wrong numbers is minimized and the capability for queuing multiple
calls at a singe address is established.
