Options for Calls that Require the IWF

You can configure several specific behaviors by configuring options for calls that require the IWF, and set them for the H.323 side of the call. These options are listed and defined in the table below. Options can be configured either globally for the H.323 configuration, individually for an H.323 interface, or for H.323 session agents.

Global Configuration for H.323

To configure options globally for H.323:

In Superuser mode, type configure terminal and press Enter.
```
ORACLE# configure terminal
```
Type session-router and press Enter to access the session-related configurations.
```
ORACLE(configure)# session-router
```
Type h323 and press Enter.
```
ORACLE(session-router)# h323
```
From this point, you can configure H.323 parameters. To view see all H.323 parameters, enter a ? at the system prompt.
Type options, a space, and the name of the option you want to use. In this example, the MapG729 will map H.245 G.729 to SDP G.729 with Annex B and vice versa.
```
ORACLE(h323)# options MapG729
```

Individual Configuration for H.323

To configure options per individual H.323 interface:

In Superuser mode, type configure terminal and press Enter.
```
ORACLE# configure terminal
```
Type session-router and press Enter to access the session-related configurations.
```
ORACLE(configure)# session-router
```
Type h323 and press Enter.
```
ORACLE(session-router)# h323
```
Type h323-stacks and press Enter. The system prompt changes again to let you know that you can begin configuring individual parameters.
```
ORACLE(h323)# h323-stacks
ORACLE(h323-stack)#
```
From this point, you can configure H.323 interface parameters. To view see all H.323 interface parameters, enter a ? at the system prompt.
Type options, a space, and the name of the option you want to use. In this example, the MapG729 will map H.245 G.729 to SDP G.729 with Annex B and vice versa.
```
ORACLE(h323-stack)# options
```

Configuring H.323 SA Options

To configure options for H.323 session agents:

In Superuser mode, type configure terminal and press Enter.
```
ORACLE# configure terminal
```
Type session-router and press Enter to access the session-related configurations.
```
ORACLE(configure)# session-router
```
Type session-agent and press Enter.
```
ORACLE(session-router)# session-agent
```
From this point, you can configure session agent parameters. To view see all session agent parameters, enter a ? at the system prompt.
Type options, a space, and the name of the option you want to use. In this example, the MapG729 will map H.245 G.729 to SDP G.729 with Annex B and vice versa.
```
ORACLE(h323-stack)# options MapG729
```

H.323 SA Options

Options	Description
MapG729	Oracle® Enterprise Session Border Controller maps H.245 G.729 to SDP G.729 with Annex B and vice versa. Applicable only to calls that require the IWF.
ColonG729	Oracle® Enterprise Session Border Controller uses the : (colon) instead of the = (equal sign) in the media attribute line a=fmtp:18 annexb=yes/no when mapping H.245 G.729 or SDP G.729 with Annex B. Applicable only to calls that require the IWF.
IwfLRQ	Oracle® Enterprise Session Border Controller sends an INVITE (with no SDP) to a redirect server in response to an incoming LRQ received on an H.323 interface. If a 3xx message with a redirected contact header is returned, the Oracle® Enterprise Session Border Controller will send an LCF in response to the LRQ. Otherwise, it will send an LRJ.
NoG729AnnexB	SDP received by the IWF with H.729 and no FMTP will be mapped to G.729 on the H.323 side of the call. Can also be set in the session agent options parameter.
sameT38Port	Oracle® Enterprise Session Border Controller’s H.323 process does not allocate separate ports for audio and T.38. Oracle® Enterprise Session Border Controller will send the same audio port in the OLCAck that it sees in a request mode for T.38 and a new OLC for T.38.
pvtStats	Oracle® Enterprise Session Border Controller includes program value tree (PVT) statistics in the show h323d display that are a sum of the PVT statistics for all H.323 interfaces. Used for debugging purposes.
acceptAl	Oracle® Enterprise Session Border Controller accepts all the codecs received in the SIP 200OK and builds the TCS accordingly.
