With the mobile versions of the app, if I am to place a phone number for a contact directly in the description of the task, it attempts to treat it as a website link, and just reports an error.
If I create the contact directly into the CRM also, it does link the contact, but I would have no way of just clicking the phone to make the call. I am still having to physically write/type out the number.
I see that there is a phone icon to the side, that it would seem like it should serve that function, but it does not.
