Abstract
A method and apparatus for recovering a call resource from a call session are disclosed. A call resource detects if a media stream communicated from a device via a communication network becomes inactive during the call session and deletes the inactive media stream. The call resource deletes the inactive media streams until one media stream remains in the call session, which is terminated to release the call resource from the call session.
