On a candidate- phone icon linking to the CRM

On a candidate- phone icon linking to the CRM

Hello,
For a couple of weeks now, I have a new phone icon next to our candidate's telephone number. When I click on it if the candidate exists in the CRM (with the same telephone number), recruit opens a pop-up box at the bottom of the page that show the candidate's business card in the CRM.  What is weird is that I (super admin) have the icon, but my colleague who is admin does not.
I have contacted support, but so far no luck.
Has anyone else had this? And could tell me more about it and if it will be developed further? As it could really help us.
Thanks
