ITU-T Recommendations

This Recommendation specifies a mechanism that allows H.323 entities participating in a stable call to temporarily suspend and later resume the call signalling channel.Further, using the procedures described in this Recommendation, an intermediate entity (such as a Gatekeeper that routes call signalling messages at the beginning of the call) may remove itself from the call signalling path once the call is stable, and establish the call signalling path directly between the other two entities.
