In a phone conversation with Michael Burrell, head of enterprise telephony at Equant, we asked about VoIP in general, and how IP VPNs can help companies looking to add VoIP to their mix of technologies, among other topics.
Networking Pipeline: What benefits can enterprises gain by moving from traditional WAN services to an IP-based VPN?
Michael Burrell: It starts with an application performance assessment. Most enterprises don't have a good handle on which applications are using bandwidth. In an assessment, you may find out that a lot of bandwidth is being consumed by applications that are not mission-critical to the business. With an MPLS-based IP VPN, you can optimize and properly size the bandwidth -- and you may even end up saving money by using less overall bandwidth, with converged services.
