Is there a time limit on the length of a message?

For all of our products, the maximum time limit on the length of an individual message is 30 minutes. That is both using the service when people call in using the phone number, as well as the time limit for calls left using the rental vintage phone. We want to encourage people to leave meaningful stories and thoughts and so there are no limits on how often people can call in, or on the total number of callers or recordings.
