I have a panasonic kx-t7250. Whenever I place a patient on hold and I don't pick up before the beep it hangs up on the person. It was programmed where I could place people on hold and it would just beep until I could pick up and it never hung up on anyone. Please help me reprogram this phone so people don't think I'm hanging up on them and I don't have to do the 50 yard dash to get to the phone before it hangs up. Thanks in advance!!!!
