TableD-5 Action Descriptions

Step Action Description

1. Local Admission Request (ARQ)—Local

endpoint to H.323 gatekeeper

Cisco ATA sends a local ARQ message to the H.323 gatekeeper

seeking authorization to place a call over the H.323 network.

2. Local Admission Confirm (ACF) or Admission

Reject (ARJ)—H.323 gatekeeper to the local

endpoint

H.323 gatekeeper returns a ACF or ARJ message, indicating

whether or not the responding gatekeeper is going to al low the

Cisco ATA device access to the network.

3. Open TCP Channel for Q.931 messaging TCP port 1720 is opened, making way for the forward and reverse

flow of Q.931 signaling messages between the H.323 endpoint

and the CSN/PSTN Gateway.

4. Q.931 Call Setup—Local H.323 endpoint to

remote H.323 endpoint

Call setup initiates from the local H.323 endpoint.

5. Q.931 Call Proceeding—Remote H.323

endpoint to local H.323 endpoint

Gateway acknowledges call setup initiation.
