20.2.5.6 Adding SIP Record-Route Header to SIP INVITE

You can configure SAS to add the SIP Record-Route header to SIP requests (e.g. INVITE)
received from enterprise UAs. SAS then sends the request with this header to the proxy.
The Record-Route header includes the IP address of the SAS application. This ensures
that future requests in the SIP dialog session from the proxy to the UAs are routed through
the SAS application. If not configured, future request within the dialog from the proxy are
sent directly to the UAs (and do not traverse SAS). When this feature is enabled, the SIP
Record-Route header includes the URI "lr" parameter, indicating loose routing, as shown in
the following example:
Record-Route: <sip:server10.biloxi.com;lr>
Notes:

To enable the Record-Route header:
1. Open the SAS Configuration page (Configuration tab > VoIP menu > SAS > Stand
Alone Survivability).
2. From the 'Enable Record-Route' drop-down list, select Enable.
3. Click Submit to apply your changes.
