Please try.

I took a handset from another base, where it works. Try to register it on the base with wrong pin. I got the same answer "wrong pin". Shortly before I connected the base with the changed pin 1234.

Last thing you can do before submit a support ticket @ Yealink is to reset the base to factory default and try to register both or more handsets to the base.
Perhaps the base allowed only one handset to register?????
