At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
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.
This is not possible, the integration only has the option to forward the email field:
I have forwarded a request to our back-end team to include the option to forward a custom field such as the phone number. Please note that this could be approved or declined, and if it is approved there is no estimated time-frame for an implementation.
You will be notified via this thread if there is any progress on this feature request.
