H.323 Signaling Scenarios


Note The term Cisco ATA is used throughout this manual to refer to both the Cisco ATA 186 and the Cisco ATA 188, unless differences between the Cisco ATA 186 and Cisco ATA 188 are explicitly stated.


Supported H.323 Messages

The Cisco ATA supports the following H.323 request methods:

Request—When registering with an H.323 gatekeeper or Gateway, an individual H.323 endpoint must begin the process by sending a request message.

Confirm—H.323 gatekeepers and Gateways authorize individual H.323 endpoints to access and send data over the H.323 network with explicit confirmation messages.

Reject—In the event that an H.323 gatekeeper or Gateway in unable to grant access permission to an H.323 endpoint, a rejection message is sent and call setup is halted.

Setup—Once access to the H.323 network has been granted, H.323 components contact remote H.323 components via setup messages, initiating two-way voice, video, or data communication.

Proceeding—When a remote H.323 component acknowledges receipt of call initiation information and agrees to perform necessary subsequent setup for two-way voice, video, or data communication, it responds with a proceeding message.

Alerting—When a remote H.323 endpoint has begun to notify the called party of an incoming call (the phone begins to ring at the far end), an alerting message is sent back to the calling party.

Connect—When the called party answers the call (the phone goes off hook), the remote H.323 endpoint transmits a connecting message notifying the calling party that two-way communication is ready to commence.

H.323 Signaling Scenarios

This section describes call flows for the following scenarios:

H.323 Endpoint-to-Gatekeeper Registration

H.323 Endpoint-to-Endpoint Call Setup with a Common Gatekeeper

Description

1.

Gatekeeper Request (GRQ)—Cisco ATA to H.323 gatekeeper

Cisco ATA sends a GRQ message to the H.323 gatekeeper to see if any gatekeepers are available for registration.

2.

Gatekeeper Confirmation (GCF) or gatekeeper Rejection (GRJ)—H.323 gatekeeper to Cisco ATA

H.323 gatekeeper returns a GCF or GRJ message, indicating whether or not the responding gatekeeper is able to register new Cisco ATA devices.

3.

Registration Request (RRQ)—Cisco ATA to H.323 gatekeeper

Cisco ATA sends a RRQ message to the H.323 gatekeeper in an attempt to register as part of that gatekeeper's zone.

4.

Registration Confirmation (RCF) or Registration Rejection (RRJ)—H.323 gatekeeper to Cisco ATA

H.323 gatekeeper returns a RCF or RRJ message, indicating whether or not the gatekeeper will add the Cisco ATA to its zone.

Table D-3 Action Descriptions 

Step
Action
Description

1.

Local Admission Request (ARQ)—Local H.323 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 H.323 endpoint

H.323 gatekeeper returns a ACF or ARJ message, indicating whether or not the responding gatekeeper is going to allow 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 endpoints.

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

Remote H.323 endpoint acknowledges call setup initiation.

6.

Remote Admission Request (ARQ)—Remote Cisco ATA to H.323 gatekeeper

(Somewhat simultaneous, chronologically, to call setup and call proceeding) remote H.323 endpoint contacts the common H.323 gatekeeper, seeking authorization to complete the two-way H.323 network call.

7.

Remote Admission Confirm (ACF) or Admission Reject (ARJ)—H.323 gatekeeper to the remote Cisco ATA

H.323 gatekeeper returns a ACF or ARJ message, indicating whether or not the responding gatekeeper is going to allow the Cisco ATA device access to the network.

8.

Q.931 Alerting—Remote H.323 endpoint to local H.323 endpoint

Status message is sent to calling H.323 endpoint advising that the called party has been notified (phone ringing).

9.

Q.931 Connect—Remote H.323 endpoint to local H.323 endpoint

Status message is sent to calling H.323 endpoint advising that the called party has answered the call (phone off hook).

10.

Open TCP Channel for H.245

Dynamically assigned TCP port is opened on both the local and remote H.323 endpoints, allowing for subsequent call setup activities (transmission and reception capability exchange, master-slave relationship determination, and so on).

11.

H.245 Terminal Capabilities

Various endpoint transmission and reception capabilities defining operation of voice, video, and data are exchanged and acknowledged to ensure consistent, reliable two-way communication between endpoints.

H.323 Call Setup from H.323 Network to Circuit Switched Network

Figure D-3 illustrates a Cisco ATA initiating a connection to a Circuit Switched Network (CSN) or Public Switched Telephone Network (PSTN) Gateway router through its local H.323 gatekeeper.


Note This scenario assumes that the H.323 configuration employs Fast Start Signaling with tunneling capability.

Table D-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 allow 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.

6.

Gateway Admission Request (ARQ)—SCN/PSTN Gateway to H.323 gatekeeper

(Somewhat simultaneous, chronologically, to call setup and call proceeding) Gateway contacts the common H.323 gatekeeper, seeking authorization to complete the two-way H.323 network-to-CSN/PSTN Gateway call.

7.

Gateway Admission Confirm (ACF) or Admission Reject (ARJ)—H.323 gatekeeper to CSN/PSTN Gateway

H.323 gatekeeper returns a ACF or ARJ message, indicating whether or not the responding gatekeeper is going to allow the Gateway access to the network.

8.

Q.931 Alerting—Gateway endpoint to local H.323 endpoint

Status message is sent to calling H.323 endpoint advising that the called party has been notified (phone ringing).

9.

Q.931 Connect—Gateway to local H.323 endpoint

Status message is sent to calling H.323 endpoint advising that the called party has answered the call (phone off hook).

10.

Open TCP Channel for H.245

Dynamically assigned TCP port is opened on both the local H.323 endpoint and the Gateway, allowing for subsequent call setup activities (transmission and reception capability exchange, master-slave relationship determination, and so on).

11.

H.245 Terminal Capabilities

Various endpoint transmission and reception capabilities defining operation of voice, video, and data are exchanged and acknowledged to ensure consistent, reliable two-way communication between the H.323 endpoint and the Gateway.

12.

H.245 Terminal Capabilities

15.

Exchange of Master-Slave Determination Messages—Remote H.323 endpoint to local H.323 endpoint

Determines master and slave assignments between the H.323 endpoint and the Gateway.

16.

H.245 Open Audio Logical Channel—Local H.323 endpoint to remote H.323 endpoint

Before actual transmission or reception of voice, video, or data, notification that the primary logical channel for the local H.323 endpoint has been opened, ensuring clear two-way communication.

17.

H.245 Open Audio Logical Channel Acknowledgement—Remote H.323 endpoint to local H.323 endpoint

Gateway acknowledges readiness.

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 Gateway 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 Between Endpoint and Gateway

Two-way communication ensues between the local H.323 endpoint and the CSN/PSTN Gateway.
