Pros: It works with our Magic Jack now we only need to plug into one phone line (our computer) to have three phones around the house. intercome is great you can select the phone you wish to comunicate with by simply selecting the # 1,2,or 3. Now we have a complete phone system that was unavailable using one connected o magic Jack. selective ring tone is nice but it doesnt engage for about 2 seconds after ringing.

Cons: voice caller ID doesn't announce until @ 3 rings which is unfortunate because Magic Jack is programmed to record calls after 4 rings.
