The server system exchanges Session Initiation Protocol (SIP) signaling with a SIP system, establishes hardware trust with the SIP system, and determines that the SIP system has established hardware trust with the second access network and a second communication device. The server system exchanges SIP signaling with a first communication device and establishes hardware trust with the first communication device. The server system receives a SIP Invite requesting a communication session between the first communication device and the second communication device over hardware-trusted systems, and based on the established hardware trust, the server system responsively forwards the SIP Invite to the SIP system for delivery to the second communication device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Session initiation protocol (SIP) communications over trusted hardware","description":"A server system exchanges trust signaling with a first access network, establishes hardware trust with the first access network, and determines that the first access network has established hardware t","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9667665","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.
