SIP Diversion Header Enhancements
The SIP Diversion Header Enhancements feature enables time-division multiplex (TDM) gateways and Cisco Unified Communications Manager Express to populate the SIP Diversion Header with a domain name. Localhost command-line interface commands can be used to configure the domain name globally or at the dial peer level. This feature also provides choice of transparent pass through or application of address hiding to the SIP Diversion Header on Cisco UBE platforms.

Prerequisites for SIP Diversion Header Enhancements
Cisco Unified Border Element
- Cisco IOS Release 12.4(22)T or a later release must be installed and running on your Cisco Unified Border Element.
Cisco Unified Border Element (Enterprise)
- Cisco IOS XE Release 3.1S or a later release must be installed and running on your Cisco ASR 1000 Series Router.
Information about SIP Diversion Header Enhancements
To enable this feature, you must first configure the sip-ua command to place the router in SIP user-agent configuration mode before you can use the host-registrar command.
By default, the Session Initiation Protocol (SIP) gateway and Cisco Unified Communications Manager Express (Cisco Unified CME) populate the host portion of the diversion header with the domain name or IP address of the gateway that generates the request or response. The SIP gateway and Cisco Unified CME also populate the host portion of the redirect contact header with the session target IP address or hostname of the matching dial peer.
When the host-registrar command and the registrar command are both configured in SIP user-agent configuration mode, the SIP gateway or Cisco Unified CME populate the host portion of both the diversion and redirect contact headers with the domain name or IP address configured by the registrar command.
The host-registrarcommand should be configured along with the registrar command in SIP user-agent configuration mode. If the host-registrar command is configured without the registrar command, the host portion of the diversion header is populated with the domain name or IP address of the gateway and the host portion of the redirect contact header is populated with the session target IP address or hostname of the matching dial peer.
