Original phone on original port and verify behavior.
Original phone on new port and verify behavior.
We had the original phone on the original port that was malfunctioning as described in the OP. We replaced the phone and got the same result. The new phone, which had the same exact behavior as the original (so it's not the phone) was moved to another port and had the same issue plus the lack of audio on the other end of a call.
