This report examines the strategic IP telephony options open to businesses: choices in the area of equipment and services (design, deployment, maintenance), alternative rollout models (hybrid, centralised, hosted), technological choices (IP phones, SIP, XML, open source), comparative costs, new uses enabled by ToIP (application services, mobility…) and with other key criteria (security, QoS…).

The report also positions the offers marketed by the value chain's main actors (equipment suppliers, service providers, integrators, operators) and analyses the competition and partnerships that exist between them.

Also included is a look at the status of businesses' migration to ToIP (take-up rate by size of company and sector of activity, the enablers and obstacles, technical and financial state of affairs…), followed by an analysis of equipment market trends and IP telephony's future prospects (are voice services going all software?)
