Sheepa.org is a free, non-profit site that hosts various stuff depending on demand. Right now there is a Ventrilo, a Mumble and two Call of Duty 4 servers up. All are open to the public and free of charge. However there might be advantages, such as being able to create private ventrilo rooms by having an account. Creating an account is completely free and will only take a couple of minutes.
