Many advantages: aesthetic, very intuitive, very good sound. Choosing whether to hear incoming calls on the answering machine, award choosing a ring tone to a particular person. Cons: few ringtones, ringtones that are not strong enough (you do not hear the sound in the basement of the house). However, I recommend it and I plan to expand the plant with an additional post. That is fact. Adding additional post is very smooth. One negative: I use with Siemens headset that can remain connected when the handset rests on the base. Consequently, it must connect and disconnect each day and what had to happen ... the headphone jack on one instrument no longer works ... Pity.
