Need to reset the security code for part #80573

NEC has many products, so I don't know what 80573 is, but you should have a system manager who can blitz the old security code so a new one can be set up. Usually that task goes to the office manager, or internal IT person.

Put lines in double hold

If it is under warranty then return it. if you alter it they won't honor it. however you can check that your wires are hooked up correctly from the phone to where it comes into your building it sounds like that is more likely the problem. your telephone provider is responsible outside of your building if they come in they will charge you. we have had a bad line in the past and had verizon put 2 numbers on one line temporarily maybe thats the case. if you don't call them to change it back they won't. Hope this helps
