SIP Event Package Interoperability Configuration

This feature is applicable to the global SIP configuration.

To configure SIP event package interoperability:

In Superuser mode, type configure terminal and press Enter.
```
ORACLE# configure terminal
```
Type session-router and press Enter.
```
ORACLE(configure)# session-router
```
Type sip-config and press Enter. The system prompt changes to let you know that you can begin configuring individual parameters.
```
ORACLE(session-router)# sip-config
ORACLE(sip-config)#
```
options—Add SIP event package interoperability support to a new SIP configuration or to an existing SIP configuration:
If you do not currently have an SIP configuration, you can add the option by typing options, a Space and then global-contact.
```
ORACLE(sip-config)# options global-contact
```
Select the SIP configuration so that you can add SIP event package interoperability support to it. Then, to add this option to a list of options that you have already configured, type options followed by a Space, the plus sign (+), and the global-contact option.
```
ORACLE(sip-config)# select
ORACLE(sip-config)# options +global-contact
```
If you type options global-contact without the plus (+) sign, you will remove any previously configured options. In order to append the new option to the options list, you must prepend the new option with a plus sign as shown in the example above.
Save and activate your changes.
