Working on an older IVX DP1 phone. Was testing out a number of headsets (could get none to work), the phone handset is failing to trigger a line pickup/doesn't work.

All other phone functions working properly.

P/H 3-3 is (re)set to disable
P/H 3-5 is set to disable

any ideas on how to get the extension to recognize the handset again?
