How do I get the DSS/BLF key to light up for outgoing calls on my MN3300 system?

If the DSS/BLF light comes on when calls come in but not when you're making calls you need to follow these steps:

  1. Login to your system.
  2. Go to the User and Device - User and Device Configuration form.
  3. Select the extension in question.
  4. Highlight the extension and click Change.
  5. Select the Keys tab and check the DSS/BLF key is programmed. If it's not, program it by selecting an Unused Key - select Change Key and add the details.
  6. Confirm the users in the Multiline group.
  7. Check that System Options - DSS/BLF - Busy on set - Enabled = Yes
