I have an NEC D-term 80 (Elite IPK II) system. There are 2 phones that have CAMP LINE displyed fulltime and one of our outside lines is tied up. When you try to hit that line, there is a busy signal.
Can anyone help me with this?
Thanks.

Go to these phones get internal dial tone and dial 770

Another trick hit the Exit Key on the top left and there is a Clear Menu this helps for MW,Camp,Rpt I think its camp or Call Back but either way feature code will always work.

Have your vendor remove the "#" from the single digit options in the system programming.

What happens is people dial voicemail, then press '#' before the greeting answers and the line gets stuck in "CAMP ON".
