The administrator of ABC company is troubleshooting a one-way audio issue for a call that uses H.323 protocol (slow-start mode). The administrator requests that you provide the IP and port information of the Real- Time Transport Protocol traffic that had the one-way audio call. You gather the H.225 and H.245 messages for one of the one-way audio calls. Where can you find the RTP IP and port information for both sides? (Note: This call flow has not invoked any media resources like MTP or transcoders).
B The Open Logical Channel shows the initiating side’s RTP details, so you get the sender’s IP and port right there without needing to wait for the Ack.
It’s B. The Open Logical Channel message kicks off the media stream and definitely includes the sender’s RTP IP and port, which is crucial for identifying where the audio is coming from.
B/D for sure, cause B has sender’s RTP info and D confirms receiver’s side.
D imo, since the Ack confirms the negotiated RTP IP and port details for both ends.
I think it’s D. The Open Logical Channel Ack message confirms the media path and has the receiver’s RTP details, which you need to troubleshoot one-way audio issues. D
B/D? The Open Logical Channel shows where the sender wants to send RTP, while the Ack confirms the receiver’s RTP IP and port. Both are needed to get full RTP info for both sides.
Option B seems off because the Open Logical Channel is more about requesting to open the channel; it doesn’t always have the final IP and port info. The Ack (Option D) confirms the channel setup and usually includes the actual RTP endpoints used by the other side. So, I’d say the RTP IP and port info for both sides is best found in the H.245 Open Logical Channel Ack message since it provides confirmation and final details after negotiation.
Maybe D makes more sense here. The Open Logical Channel message sets up the channel, but I think the actual IP and port info for RTP usually come back in the Ack message. So, you get confirmation of the media path details in the Ack, not just the request. That fits with how H.245 works for establishing media streams. A and C don’t carry this kind of media endpoint info, and B is more about the initial channel setup without confirmation.
B/D? The Open Logical Channel message usually carries the RTP info for sending, while the Ack confirms it. A and C seem less likely since capability set and connect don’t usually have detailed media endpoints.
