H.323 Admission Control Configuration

You can configure the endpoint to allow accept and process requests from a H.323 realm. If a request does not meet the criteria you set here, it is rejected.

To configure admission control:

In Superuser mode, type configure terminal and press Enter.
```
ORACLE# configure terminal
```
Type session-router and press Enter.
```
ORACLE(configure)# session-router
```
Type h323 and press Enter. The system prompt changes to let you know that you can begin configuring individual parameters.
```
ORACLE(session-router)# h323
ORACLE(h323)#
```
Type h323-stacks and press Enter. The system prompt changes to let you know that you can begin configuring individual parameters.
```
ORACLE(h323)# h323-stacks
ORACLE(h323-stack)#
```
Set the criteria upon which you want to base admission control.

allow-anonymous—Enter the anonymous connection option (mode) you want applied to the processing of H.323 requests. The default value is all.

The following are valid values:
- all—No ACL is applied and all anonymous connections are allowed.
- agents-only—Only requests from configured session agents are processed.
- realm-prefix—Only requests from session agents and addresses matching the realm’s address prefix are processed. All other requests are rejected.
  
  The following example shows the allow-anonymous parameter has been configured to allow only requests from configured session agents. All other h.323-stack parameters are omitted for brevity.
```
h323-stack
allow-anonymous                agents-only
```
