I would love to know the answer to this question. Alternatively, I wonder something else: When they say "this call may be recorded" could you legally interpret "may" to mean as giving you permission, rather than as "might be recorded"? It would seem like they might have a hard time arguing "this call may be recorded for quality purposes" doesn't imply that you may (= can) record the call for quality purposes.
