Calliflower provides unlimited conference calls. There is no additional charge for calls based on size, frequency, or number of participants. Calliflower is billed at a flate rate per "organizer" on a monthly basis.

The theoretical maximum size call we can handle is over 900 participants. In practice, our largest calls have been around 200 people. Please drop us an email at support@calliflower.com if you plan to hold a very large call. We'll do our best to help you make it successful.
