i been using youmail, it works great for me and it has really nice options like smart voicemail .. meaning if lets says your wife calls you and whatever you have her under your contact list name and you cannot pick up the phone it will greet her by the name you have her listed in contact and mention your name ..for ex-sample , Hello wife , david cannot come to the phone right now etc ...it works good .. you can leave special voicemails greetings for individual people on your contact list , or blocked numbers etc , you can log in to the site and download the voicemails on your computer or on the app itself you have the option to forward them to emails , text Bluetooth etc ..and its free with up to 200 voicemail if you want more space .. you can paid like 20 bucks a year
