Current Disconnect
This is a preconfigured value of duration for a line power drop used by specific service pro-
viders. For example, for a configured value of 500ms the device will ignore any random
voltage drops on the line if duration of such drop is less than 500ms and the call will NOT
be considered as terminated. This is useful to prevent unnecessary call drops in some low
quality PSTN lines.
Enable Tone Disconnect
Default is Yes. If set to Yes, busy tone is used as disconnect signal.
