  1. Sir, i have been using dynamic lock system for a very long time. but now due to wrong typing code, it is not accepting locking system. whenever I try to close the landline, it says to check the number dialed.
    Now I am not able to lock or use dynamic lock system, and it has become a big mess. Please advise and do the needful.
    Thank you.
