Microsoft Dynamics CRM Online outbound phone calls default to Lync instead of Skype

When clicking on a phone number attribute that is valid for Skype integration, such as the out-of-the-box "Mobile Phone" field on the Contact entity, Lync attempts to dial the call instead of Skype.


This issue can occur if Lync is installed after Skype, as this sets the default CALLTO protocol program to the last installed telephony provider. The issue can also occur if the default CALLTO protocol handler has been manually changed in the Control Panel. 


Change the default program for the CALLTO: protocol from Lync to Skype.

  1. Access the Start Menu and click Control Panel

  2. In the View by: field, under Category, select Large Icons

  3. Select the Default Programs applet

  4. Click "Set your default programs"

  5. Select Skype from the list and then click "Choose defaults for this program"

  6. Select the CALLTO protocol in the list and click Save

  7. Click Ok
