All Contact Fields Optional
It would be great to leave all contact fields optional and or the possibility to change the validation (regex) of the predefined fields.
For example, on my website I don't request users name nor e-mail. I only need his phone number and some other fields.
I think the system groups all the calls by the email entered in the service but I also agree that it could be by another identification such as CPF, CNPJ, not to have to type email every time.
That would be very interesting.
