This feature allows users to receive alerts when a phone is off the hook and idle. When it is enabled, the phone dials a preconfigured extension in the following cases:
  • A user takes the handset off the hook and does not dial any digits for a set period of time after that.
  • A user takes the handset off the hook, dials an incomplete or invalid phone or extension number, and does not end the failed session after a set period of time.
When the phone dials the off-hook alert destination extension, a user then has a two-way talk path with the monitoring extension.
You can configure this feature using the 46xxsettings.txt file.
Note:
Phone lock and Shared Control features must be disabled for off-hook alert to work.
