The default value is True.
To stop the Cisco CallManager from considering # as end-of-dialing, set this parameter to False. This allows Cisco CallManager to send #.
To set the value of this parameter, choose Service > Service Parameters > CallManager service on the Cisco CallManager Admin page, and look for this parameter
