We’ve reviewed quite a few Twitter apps but it’s not often that we come across something really quite ingenious. Twit2Tel allows any Twitter user to create their own free voicemail account and make free calls to anyone. The system seems very polished, users can sign in using their Twitter or Linkedin accounts, it might be interesting to add Facebook Connect to that list too.

A very smart and logical mashup of Twitter, we’ve already received our first voicemail to @startupwizz and can see Twit2Tel being useful for Twitter users with large follower lists. We receive far too many direct messages to ever keep track of on Twitter, but a Twit2Tel voicemail message would never be ignored.
