For those of you who don’t think voicemail is counterproductive, there is a new app on Facebook called Voicetag that lets you send voicemail messages to individuals or groups. This is not the first such app on Facebook (see Voicemail or TringMe), but it works with regular phones and incorporates SMS messages.
The app is very simple. You select a Facebook contact you want to leave a voice message for (or you can set up group aliases), and add an optional text message. Then, instead of using a computer microphone, you enter the number where you are at and Voicetag calls you. After leaving your message, the recipient gets a notification via Facebook and can play the Voicetag from his or her browser. You can also leave messages to groups from your cell phone by texting Voicetag. It will then call back your cell phone and you can leave a message. The service is free for now.
