The communication transceiver is configured to receive a first session initiation protocol (SIP) information message comprising a request for directory assistance data, wherein the request is expressed in an extensible markup language (XML) format. The processing system is configured to query a directory assistance database to retrieve the directory assistance data and process the directory assistance data to generate a second SIP information message comprising the directory assistance data expressed in the XML format. The communication transceiver is further configured to transfer the second SIP information message for delivery to the WebRTC engine."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Information exchange between a directory assistance application server and a web-RTC engine","description":"A directory assistance (DA) application server to facilitate directory assistance lookup requests involving a web real-time communication (WebRTC) engine comprises a communication transceiver and a pr","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9705993","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.
