How to disable Skype and Lync telephony providers for Dynamics CRM completely

Question

How can we disable the Skype and Lync providers completely from Dynamics CRM 2015 Online in either supported or unsupported way?

What I have tried so far:
- Created my own link on phone number fields
- Tried to locate any jQuery event handlers attached to the element in the DOM
- Assigned the blank event handler to Mscrm.ReadFormUtilities.handlePhoneNumberClick (Ref: http://crmtipoftheday.com/2014/05/15/how-to-block-click-to-call-in-crm/)

Still when I click on the phone number the Dynamics create a blank page and activates an inline phone call record.

And when I run

frames[0].$('#telephone1 div span a').click();

from browser console, it doesn't create a blank page or an inline phone call record.

NOTE: This was not happening prior to CRM 2015 Update 1 or in Update 1 legacy form rendering.

Any ideas?

After debugging action.js, formcontrols.js and global.ashx and try hitting several times I caught the point in Mscrm API that was opening a new window for default telephony providers (Skype/Lync).

This script disabled the default telephony completely. Use with caution and test carefully before deploying to production environment as this is not supported.

Mscrm.ReadFormUtilities.openPhoneClient = function () { return; }
