# Channel functions

MSPP channels provide a way to transform streaming media that flows between two endpoints. Channels are made up of one or more channel filters. Filters are parameter-driven functions that perform a series of specific actions on the media flow. This set of filters is referenced by an alphanumeric channel name.

Function | Synchronous/ Asynchronous | Description
mspCreateChannel | Asynchronous | Creates and configures an MSPP service media channel. The type of channel is specified in the ADDR structure with an alphanumeric value.
mspDestroyChannel | Asynchronous | Destroys a channel.
