Door call forwarding<br />

All door calls are automatically terminated after a specific time interval has expired (default is 60 seconds).<br />
This ensures that forwarded door calls do not unintentionally lead to continuous calls (e.g. to a voicebox).<br />
Your system administrator can configure the time interval in the <strong>Comfort</strong> <strong>Pro</strong> from 30 to 300 seconds and will<br />
be able to tell you the current value.<br />
