IWF Inband Tone Option
This option enables the Oracle Communications Session Border Controller to send a progress indicator (PI) =8 in an H.225 message when an SDP is received in a provisional message. In effect, this option sends network announcements inband. It is also applicable because in some networks H.323 endpoints support early H.245.
The H.323 inband tone option is enabled by adding the inbandTone as an option in a configured H.323 stack.
When this option is not used, the ringtone is generated locally (NO PI=8 in PROGRESS OR ALERTING) is the default behavior.
