Is FMC driving the transition to IMS? For service providers, that depends! How are you positioned in the market? Who are your target customers? When do you want to roll out the service?

BT is already on the path to IMS with its 21CN rollout. FMC in and of itself is not driving the migration for BT, though it is the deployment of FMC and converged services like it that are. Is FMC driving the transition to IMS?
