The first SIP INVITE with replaces header message comprises a Session Description Protocol (SDP) offer and a first request Universal Resource Identifier (URI) that identifies the first communication application. In response to receiving the first SIP INVITE with replaces header message, a second SIP INVITE with replaces header message is sent to a second communication application. The second SIP INVITE with replaces header message is used to reestablish all the SIP failed dialogs in order to reestablish the original communication session and reestablish the original media stream."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Call preservation for multiple legs of a call when a primary session manager fails","description":"In response to a failure of a SIP dialog between a first communication endpoint and a first communication application (i.e., when a session manager fails), a first Session Initiation Protocol (SIP) IN","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10469538","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.
