Multi-carrier terminations…
• Call-by-call termination leverages cost benefits of multiple carriers & improves performance
• Multiple IP termination points across enterprise provide inherent redundant paths
• Multiple carriers inherently provide greater reach

• Providing voice and data services to a business over a “converged” network connection.
• Narrowband Voice Services are broken out separately at the customer premise using a “media gateway”.
• Providing broadband voice and data services to a business over a “converged” network connection.
• Voice services are broadband or “all IP” to the telephony device.
• Full service• No expert
staff needed• Low initial
investment
• Economics of V+D convergence
• Economics convergence
• Enhanced Services
• Lowers CapEx
• Little to no “control”
• Restricted Capabilities
• Narrowband service – limited services
• Personnel costs
• CapEx
• Personnel costs (compared to VoIP centrex)

communication services among enterprises• However, with all-IP connectivity…
