Why compare only two or three phone providers?
A qualified shortlist reduces noise. Providers should reach the meeting only after they fit the customer’s workflow, technical environment and commercial requirements.
What should be designed before requesting quotes?
Document users, numbers, call flows, queues, integrations, reporting, compliance needs, devices, locations and migration timing before comparing proposals.
Who should manage number porting and launch?
One accountable advisor should coordinate the old carrier, new provider, network team and customer so that porting, configuration, training and contingency plans stay aligned.
