Hi Ken and welcome to JustAnswer,

Thank you for the question and your patience. Should you still need assistance for information purposes only...

Initially, is this a fresh/new install? ...or has it been installed/in service for some time already and this issue just recent?

Still, proposed preliminary tries (if have not been done):

  • • check the headset jack; and/or
  • • try a different headset.

All others would be internal.
