PROBLEM TO BE SOLVED: To provide a communication device, a communication control method, and a communication control program that can avoid the continuation of excessive current flow even if a connector of telephone lines of a business phone system is connected by error with a connector of telephone lines of a communication device after a predetermined prescribed time for voltage and current adjustment passes.SOLUTION: A communication device 100 can be connected with telephone lines L and L' by using a silicon DAA 110, and includes a control unit 170 for setting an adjustment period for adjusting the voltage and current of the telephone lines L and L'. The control unit 170 determines whether or not, the silicon DAA 110 is connected with the telephone lines L and L' after off-hook, and increases the adjustment period if it is not determined that the silicon DAA 110 is connected with the telephone lines L and L'.SELECTED DRAWING: Figure 1 |
