I'm in the US. My previous employer had a ringcentral account and I had the mobile app on my iphone with my direct line logged into it.

I left that job and started my own company in April. I deleted the ringcentral app from my iPhone.

I set up a ringcentral account for my new company about a month later and reinstalled the ringcentral app on my iPhone. I also downloaded the windows app on my new laptop. Ever since, I regularly get video chat calls for my old company number even though I'm not logged in to that account on either my laptop or my iPhone.

For instance - this morning, a former co-worker started a video chat with the person who replaced me and another new employee. The video call came through on both my personal iPhone and my new laptop windows app and when I answered it, the person who replaced me also answered. So she and I are both getting notifications when someone calls her number.

My replacement has said that they have removed all references to my personal cell phone number from RingCentral and my Windows App has never been logged into that old account. I don't know how they became linked.

How do I stop this? I am on good terms with my replacement and former employer, so if the changes need to happen on their side, I just need to tell them what to do.
