Audio crackling only happens at the office and not at home

[Jenny King]

I work a hybrid schedule in home and in office.  At home, I have no issues with Cisco Jabber.  When in the office and connected to their VPN, I have audio crackling on all external calls.  I can use Jabber to call internal people in my company with no issues.  I have replaced my computer, my headset, my ether net cable, power cord, docking station......nothing works!  On the external calls the other person can hear me just fine, but I can't hear anything but crackling and maybe every 10th word.  Someone please help!

Hi

 Per your description I would say the problem is on the internet link. But, to make sense the problem should happen with everyone on the office when calling external.
