content: Siemens had a good concept with the 2415, but the audio quality is poor. The hissing/buzzing sound was very irratable and could not be eliminated, regardless of how many times the phone was deregistered or unplugged.No indication on the base station of the number of messages was a minor inconvenience. Don't try to prop the phone between your ear and shoulder unless you have a massage therapist on retainer.Battery life is no where near the specifications. Although the idea of being able to replace the batteries with standard rechargeables is attractive, having only two AAs for power is probably the reason by the talktime is limited (most other cordless have three custom batteries).Overall, I would stay away from this phone; I replaced it with the Panasonic 2570B; so far so good.
