Google Voice

[tehshroom]

My brother just sent me a Google Voice invite and I'm having a hard time deciding which service I want. Google Voice with my existing number:

• Google voicemail: voicemail like email
• Voicemail transcription: read what your voicemail says
• Custom greetings: vary voicemail greetings by caller
• International calling: low cost calls to the world
• Notifications: read voicemail messages via email or SMS
• Share voicemails: forward, embed, or download voicemails

Add a Google Voice number to get these additional features:

• One number: a single phone number that rings all your phones
• Free SMS: send, receive & store text messages online
• Block calls: send unwanted callers straight to voicemail
• Record calls: record phone calls and store them online
• Conference calls: join several people into a single call
• Screen callers: hear who is calling before you pick up

Anyone familiar with any one of these choices? Input? Btw, once I set mine up I'll have two invites to give out.
