I am very interested in this software but I am curious of where its headed. I don't mind free software but would be willing to pay for all the features I'm looking for. Will it continue to be free? Is there a feature list for future paid versions? It appears there is currently no voicemail, how far off is voicemail integration? This package looks as close to what I'm looking for as I've seen but before I even attempt to test it I'd like to see what the future is. Also for those of you using it in a production environment are you happy with it?
