Toll-free subscribers are generally assessed a cost based on each exchange plus the duration of the call. Subscribers are also limited to the decades old technological standards of PSTN switching. It is therefore an object of the present disclosure to minimize the number of exchanges, promote technological possibility and simplify the process of directing a toll-free telephone call by providing a toll-free exchange."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Routing of toll-free numbers using a toll-free exchange","description":"Aspects of this disclosure are directed to a method of routing toll-free telephone calls using a toll-free exchange, thereby minimizing the number of hand-offs, increasing the technological capability","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9807249","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
