Both the routing and processing can be based on rule sets detailed in emergency call handling profiles (ECHPs). Any entity (e.g., SIP servers, switches, terminals, etc.) within the system can process and route the emergency call by executing the rule sets within the ECHPs associated with the call. The ECHPs are delivered to the entities within the system by value or by reference. A SIP server, e.g., may execute all or a subset of the rule set, and may communicate with an application server to execute other subsets of the rule set."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Systems and methods for exchanging call routing policies for voice over IP calls","description":"An emergency call handling system can provide emergency call routing and processing that compliments or modifies the routing and processing provided by conventional enhanced 911 (E-911) and next gener","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8526576","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.
