Calls between a customer and an agent often require additional processing of the media in real time. Processing every call in such a manner is often unnecessary and the results deleted or ignored, or prohibited due to a policy for certain calls. Knowing if a call should be processed may be determined too late for the media to be forked. While the customer and agent may engage in the call as a peer-to-peer connection, additional processing requires holding the initial invite long enough, such as with a preservation message, that a session boarder controller may fork the call for subsequent processing without timing out.
