dialogTransparency flag under the Zone object passes dialogs transparently for SIP messages processed in that specified zone. If dialog transparency is disabled, the SBC translates the dialog identifiers in the Target-Dialog header received in INVITE and REFER messages and sends the Target-Dialog header with translated dialog identifiers on the other leg. If dialog transparency is enabled, Target-Dialog header translation is not performed. However, the header is transparently passed if configured in transparency profile.
dialogTransparency flag must be enabled on both ingress and egress zones because if the flag is only enabled on one zone, all calls and messages are rejected. In this situation, the alarm is raised on the zone in which the flag is disabled.
For feature functionality, please see Dialog Transparency.
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 IPSP flags in these scenarios because the flags will be retired in upcoming releases.
Refer to the SBC SIP Transparency Implementation Guide for additional information.
