Corporate VPN on macOS disconnects when I answer a call on my iPhone while connected to local Wi-Fi. Why could this be?

I work from home so I connect to my corporate VPN from my MacBook Pro (M1 Max/16"). My MBP is hardwired to my network. Any time I get a call on my iPhone while I'm connected to Wi-Fi, the VPN connection drops as soon as I answer the call. While my iPhone is ringing, I see a notification on my MBP for the call. I am not interacting with this Continuity notification. I am answering the call on my iPhone. The VPN connection stays up while the phone is ringing, it's not until I answer it that it drops. This doesnt happen if I have Wi-Fi disabled on my iPhone. Any ideas on what could be causing this? I'm running macOS 14.2 and iOS 17.2 but this has been happening for months on prior OS versions.
