I always take every opportunity I get to point out that MPLS is not a requirement for QoS, but of course the enterprise is not actually implementing 'MPLS the technology' they are using MPLS as a nickname for 'MPLS-based IP-VPNs'. An MPLS-based VPN does offer the sort of QoS they need vs. their legacy ATM or Frame Relay network, but it is not necessarily the only option for deploying QoS in the enterprise WAN in support of a VoIP migration.

I would have hoped that a reporter working for network world would have corrected the terminology in his article on behalf of the IT people he interviewed, especially a reporter who states MPLS as one of his specialties.
