        "a": "They cover the exact same territory: the City of Boston and its immediate inner suburbs. 857 is the all-services overlay added in 2001; 617 is the historic 1947 code. Number availability may vary between the two."

        "q": "How can I confirm the price of an 857 line?",
        "a": "Cost depends on the plan, number of users and telephone configuration. The pricing page outlines the offers, while a demo confirms the applicable amount in US dollars."

      {
        "q": "What determines the activation time for an 857 number?",
