The RTP Media Portal handles Network Hiding for the media stream. For information on the RTP Media Portal, refer to the MCP RTP Media Portal Basics document.

Note: The SIP Application Module cannot map SDP information without an RTP Media Portal. It only performs address mapping for SIP header fields. Therefore, SDP passes through untouched. If the server must map SDP address information, then you need an RTP Media Portal.

The SIP Application Module is configured to use an RTP Media Portal to originate and terminate media streams (RTP/RTCP). The

SIP Application Module uses extended Media Gateway Control Protocol (MGCP+) to allocate and release resources on the RTP Media Portal for each session as needed.

Enterprise Clients

The SIP Application software uses the RTP Media Portal to hide sensitive IP address information about SIP clients behind a firewall in an Enterprise network. The exception to this occurs when the originator and terminator of the request are both part of the same network. This status is determined by checking the domains in the From header and Request-URI of the SIP Invites. If both SIP clients belong to the same Enterprise network, the SIP Application Module does not use the RTP Media Portal. Administrators can override this behavior by provisioning the AlwaysUseMediaPortal domain parameter in the Provisioning Client (for more information about this parameter, see the SIP Provisioning Client User Guide). See Figure 6, “RTP Media Portal interworking with Enterprise or foreign clients.”
