Abstract: A system and process for accepting, assigning, and delivering telephony communications data between computer telephony integration clients and stored program control point applications through a server-based virtual circuit management system. The virtual circuit management system includes an I/O Vector object array. Objects instantiate uniquely with logical identification properties, telephony data and a vector for data delivery to either clients or applications. The logical identification allows data managed by the virtual circuit management system to be persistent in both the source and destination systems. In this process, bytes of data are read into the object array from the server's operating system's input/output process. Object instances are created within the Vector object array through a process based upon the properties inherited from the data written from the I/O system.
