/mcpDescription Setting If you want Unified Communications Manager to accept new SIP dialogs, which have replaced existing SIP dialogs, check this check box. If you checked the Enable Application Level Authorization check box, go to the Application User Configuration window and check the Accept Header Replacement check box for any application users that are authorized for this method. Accept Replaces Header If you want Unified Communications Manager to transmit the security icon status of a call from the associated SIP trunk to the SIP peer, check this check box. Default: This box is not checked. Transmit Security Status From the drop-down list, select one of the following filter options: • Use Default Filter—The SIP trunk uses the default filter that is indicated in the SIP V.150 Outbound SDP Offer Filtering service parameter. To locate the service parameter, go to System > Service Parameters > Clusterwide Parameters (Device-SIP) in Cisco Unified Communications Manager Administration. • No Filtering—The SIP trunk performs no filtering of V.150 SDP lines in outbound offers. • Remove MER V.150—The SIP trunk removes V.150 MER SDP lines in outbound offers. Select this option to reduce ambiguity when the trunk is connected to a pre-MER V.150 Unified Communications Manager. • Remove Pre-MER V.150—The SIP trunk removes any non-MER compliant V.150 lines in outbound offers. Select this option to reduce ambiguity when your cluster is contained in a network of MER-compliant devices that are incapable of processing offers with pre-MER lines.
