We would like to use a RingME button (https://support.ringcentral.com/article/How-to-setup-a-Ring-Me-button-on-my-page.html) but instead of having the customer enter his/her phone number in a new screen, we would like to pass the phone number for customers who are logged into our website on a post or a get variable directly to the ringcentral server or at least to the new window and dial to make it easier for the customer.
How can we get that done?
