SIP Via Transparency Configuration

You can configure SIP Via header transparency for the access SIP interface using the ACLI.

To configure SIP Via header transparency for an access interface:

In Superuser mode, type configure terminal and press Enter.
```
ORACLE# configure terminal
```
Type session-router and press Enter to access the media-level configuration elements.
```
ORACLE(configure)# session-router
ORACLE(session-router)#
```
Type sip-interface and press Enter. The system prompt changes to let you know that you can begin configuring individual parameters.
```
ORACLE(session-router)# sip-interface
ORACLE(sip-interface)#
```
You can either add support to a new SIP interface configuration or to an existing SIP interface configuration:
For a new SIP interface configuration, you can add the option by typing options, a Space, and then via-header-transparency.
```
ORACLE(sip-interface)# options via-header-transparency
```
For an existing SIP interface configuration without options configured, select the SIP interface, type options followed by a Space, and then via-header-transparency.
```
ORACLE(sip-interface)# select
ORACLE(sip-interface)# options via-header-transparency
```
For an existing SIP interface configuration with options configured, select the SIP interface, type options followed by a Space, the plus sign (+), and the via-header-transparency option.
```
ORACLE(sip-interface)# select
ORACLE(sip-interface)# options +via-header-transparency
```
Save your work using the ACLI save or done command.
