JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
If I understand your concern correctly, you want to receive a phone call once a user has submitted your contact form. Unfortunately, this is not possible. However, you can setup an email notification instead. When you setup an email notification, you can receive an email whenever a user submitted your form. To setup an email notification in your form, just follow the instruction provided in this article: Setting Up Email Notifications.
