The higher the setting, the easier to detect silence and hence easier to trigger a disconnection. The default is medium. Disconnect Tone This is the tone script which describes to the SPA the tone to detect as a disconnect tone. The syntax follows a standard Tone Script with some restrictions. Default value is standard US reorder (fast busy) tone, for 4 seconds. Restrictions: 2 frequency components must be given.

The default is 30.
Silence Threshold
This parameter adjusts the sensitivity of PSTN silence detection. Choose from {very low,
low, medium, high, very high}. The higher the setting, the easier to detect silence and
hence easier to trigger a disconnection.
The default is medium.
