Is it possible to get the user's phone number in classmates applications?

Question

Classmates

I want to create an iframe application. In a simplified form, this is an html form in which the user asks their legal question, which is redirected to a lawyer. However, for the lawyer to communicate with the user, it is necessary to transfer contact information (it is most convenient for the user if it is a phone).
However, the phone request violates the rules for placing Odnklassniki applications.
Do I have the right to create an application that requests the user's phone for further communication with him when providing the service?

Answer 1

No, the request for personal data is also prohibited for applications that are set to OK.
The only way to somehow contact OK in this case is to create an external site with the application and use OAUTH authorization.

Answer 2

I think that applications will never be allowed to get users' phones via API. Think for yourself how many "bad" things can be done in our time with the help of a phone number and knowledge of the person's full name.
What prevents the form of correspondence with a lawyer from asking the user to manually enter the phone number? After all, the phone on OK does not always coincide with the current user's phone.
