H.323 BIS Enabled
There are certain cases in access deployments where the slow-start to fast-start conversion should not be applied. This is the case when the Setup message contains the Bearer Capability information element (IE), which signals BIS.
When you enable this feature and the Oracle® Enterprise Session Border Controller receives an incoming Setup message that does not contain a fastStart field, the Oracle® Enterprise Session Border Controller checks for the BIS in the incoming Setup before it starts to perform the slow-start to fast-start conversion. If it finds the BIS, then it does not perform the conversion.
This feature can be enabled on a global or a per-interface basis, meaning that you can apply it to your system’s entire H.323 configuration or you can enable it only for the interfaces where you want it applied.
