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.
