An identifier is generated to identify the voice call. During a first portion of the call, the voice communication is provided using a packet switched technique that includes conveying packets of voice data between the first and second apparatus via a communication connection. The communication connection is labelled with the identifier. During a second portion of the call, the voice communication is provided using a circuit switched technique that includes allocating a defined route to convey voice data between the first and second apparatus. Also during the second portion of the call, the identifier is used to manage said call."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Communication method for voice calls","description":"A communication method capable of providing voice communication between a first apparatus and a second apparatus includes establishing a voice call between the first apparatus and second apparatus to ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8520666","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.
