Cross-process media handling in a voice-over-internet protocol (VOIP) application platform

A computer-implemented system is provided that facilitates implementation of a voice-over-IP (VOIP) application. The system includes a host system and a user interface (UI) host process residing on the host system. The system also includes an agent host process residing on the host system which is being configured to process a VOIP call received by one or more VOIP applications executable on the host system. A moniker protocol is utilized for redirection of input and output between a media element which is utilized to render media on a display on the system. The redirection enables media processing to be allocated between the UI host process in the foreground and the agent host process in the background to thereby reduce latency perceived by a user during a VOIP experience.
