International Peering with IWF and H.323 Calls

When you do not enable this feature, SIP to H.323 IWF calls default to a National Q.931 Number Type and it is not possible to change it to an International number. This feature allows you to override that behavior by configuring the option cpnType=X, where X is an integer that maps to various Q.931 Number Types. When this option is set, Q.931 Number Type for both calling party and called party are updated to the configured value for all outing calls on the h323-stack.

The following is a list of possible cpnType=X option values for X:

0—Unknown public number
1—International public number
2—National public number
3—Specific public network number
4—Public subscriber number
5—Public abbreviated number
6—Private abbreviated number

International Peering Configuration

You configure this feature as an option in the h323-stack configuration.

To configure the cpnType=X option for H323-H323 calls:

In Superuser mode, type configure terminal and press Enter.
```
ORACLE# configure terminal
ORACLE(configure)#
```

Type session-router and press Enter.

ORACLE(configure)# session-router
ORACLE(session-router)#

Type h323-config and press Enter. The system prompt changes to let you know that you can begin configuring individual parameters.
```
ORACLE(session-router)# h323-config
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-stack
ORACLE(h323-stack)#
```
Set the options parameter by typing options, a Space, the option name cpnType=x with a plus sign in front of it, and then press Enter.
```
ORACLE(h323-stack)# options +cpnType=x
```
If you type options without the plus sign, you will overwrite any previously configured options. In order to append the new options to the h323-stack’s options list, you must prepend the new option with a plus sign as shown in the previous example.
Save and activate your configuration.
