Step 6: Try a Different Phone
Disconnect the phone from the ICM and connect another phone in its
place (use a phone that you know is working properly). If you are then
able to place a call with the new phone, the phone you were using is
faulty.
Step 7: Verify the Phone Is Connected Properly
Make sure your phone is connected to one of the active RJ11 "Voice
Line" jacks on the ICM ("Voice Line 1" is the primary jack). If you are
not receiving calls as expected via a virtual number, make sure your
phone is connected to the "Voice Line" jack that is assigned that
virtual number.
