A core telephony network of a telephony service provider is monitored for anomalies. Upon detecting an anomaly, it is determined whether the anomaly is significant enough to warrant re-routing inbound toll-free calls around the core telephony network. The re-routing process comprises accessing an industry registry database including a plurality of toll-free numbers (TFNs) associated with a routing template comprising the instructions for routing toll-free calls. The routing template instructions may be switched to re-direct toll-free calls associated with one or more specific TFNs to a particular carrier. Within that particular carrier, the routing instructions may be switched to re-direct the toll-free calls away from the service provider's core telephony network to a network bypass cloud platform. The network bypass cloud platform may be configured to receive toll-free calls, determine a customer telephony network to which to route the received toll-free calls based on the TFN of the toll-free call, and route the toll-free call to the customer telephony network."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Core network bypass for toll-free calling","description":"Techniques are described for determining when and how to re-route toll-free calls around a core telephony network experiencing significant disruptions.
