about foonz - free (cellphone) conference calling

With Foonz you can get a group of people on a call instantly or leave them all a message from your cell or home phone, anytime, without pre-planning. It's easy to get started. Set up a free account here and add people to your foonz contact list. Then dial the “foonz number” you'll get when you sign up and start a free group call or leave a group message! When you start a group call, foonz instantly “invites” people to join your call by sending a text message to their cell phones. They simply dial the number in the text to automatically join your call! A group can be any size. If you don't have time for a call, you can record a message for the whole group and foonz will invite them to call in and hear your message.
