Integration Code
When DTMF tone Integration is activated, the KX-TD500 informs the VPS (Voice Processing
System) of the status of the call (busy, answered, ringing, etc.) by sending a code with DTMF
tone before sending the normal call progress tone (busy tone, ringback tone, etc.).
These codes enable the VPS to immediately recognise the current status of the call and improve
its call handling performance.

Default 1
Value Range Up to 3 digits consisting of 0-9, or #
Description/Function Specifies the Ringback Tone code.
