H.323 Signaling Scenarios
18. H.245 Open Audio Logical Channel—Remote H.323
endpoint to local H.323 endpoint
Before actual transmission or reception of voice, video, or
data, notification that the primary logical channel for the
remote H.323 endpoint has been opened, ensuring clear
two-way communication.
19. H.245 Open Audio Logical Channel
Acknowledgement—Local H.323 endpoint to remote
H.323 endpoint
Local H.323 endpoint acknowledges readiness.
20. Bi-Directional Audio with Transcoding in the
Endpoints
Two-way communication ensues between endpoints over the
H.323 network.
