Actually, had this same thing. Figured out that it there is a noise reduction setting that caused it for me. Settings -> My Device -> Calls

I know this is a long shot but have you tried shooting canned air into the mic and speaker, or using a headset? Canned air has fixed two mystifying problems for us, and it seems equally likely that this random behavior is caused by hardware.
