I need to verify some claims made by incumbents in Canada that VoLTE
data travels on a totally separate channel between the phone and the

Typically it travels on another "bearer" compared to Internet traffic.

Think of bearers as "tunnels" between the mobile core network and the
device. They have a lot in common with ATM PVCs in that they can have
different QoS characteristics. So the VoLTE bearer can have scheduling
priorities that means it'll always be low-latency and highest priority,
meaning it might work well when the "Internet" bearer does not.
