Phone not ringing on telus callback

Hoping someone can help here. I booked a callback from Telus yesterday so I can discuss my internet plan. I went to great effort to be available at the appointed time, since they don't do callbacks outside business hours. My phone did not ring once, however I did receive two voice mail messages from a Telus auto attendant asking if I wanted to connect. I tested my phone by calling it and it rang, so I'm confused why it didn't ring when Telus called. Also, no number showed up in my call log either. I get every type of spam call under the sun, but I can't receive a call from Telus apparently.

Any help is appreciated. My phone is a two year old Pixel Android on a non-Telus carrier.
