Sharepoint page doesn't redirect to Jabber chat

Hi,

Currently, I am working on my company Sharepoint page and I added a couple of people as a contact at a bottom of a page.

When trying to click over a contact and call them it's working and instantly redirect to Jabber call, same when trying to send an e-mail and redirect to Outlook, unfortunately, when trying to IM, nothing happens, doesn't redirect to Jabber Chat.

Can someone provide a reason why this is not working or a method to approach this issue?

The company uses Jabber(11.8.3) and Office 365

Thank you!
