This screen helps you to understand the SDP Transparency control to set the SDP Transparency State flag to transparently pass SDP information.

To View and Edit SDP Transparency

On the SBC main screen, go to Configuration > System Provisioning > Category: SIP Carrier Peering > Signaling > SDP Transparency. 

 SDP Transparency can be checked for each Address Context, for each Zone, for each Sip Trunk Group created or for all the Address Contexts, Zones and Sip Trunk Groups created. Use the drop-down box to select the desired Address Context, Zone and Sip Trunk Group.

The Edit SDP Transparency window is displayed.

IMPORTANT

The Transparency Profile is the recommended method of configuring transparency on the SBC Core for new deployments as well as when applying additional transparency configurations to existing deployments. Do not use IP Signaling Profile flags in these scenarios because the flags will be retired in upcoming releases.

Refer to the SBC SIP Transparency Implementation Guide for additional information.
