Unknown calls are showing in FaceTime history on Macbook, but not iPhone.

The numbers shown are all different, but all list the username "Jabber" under Home. I'm running Somona 14.6.1 on a Macbook Pro. I rarely use FaceTime and then only to contact one number, which is the only one that shows up on my iPhone call history. The Macbook FaceTime call history shows multiple calls to different numbers every day, none of which are from my contacts. Has anyone run into this issue?
