Particularly, rather than select an initial codec for the connection arbitrarily or based on data measured during the connection, embodiments analyze attributes of data exchanged prior to connection establishment to identify the appropriate initial codec. Attributes of the offer message transmission and acknowledgement may be used to infer channel quality. Signal strength, the existence of a WiFi connection, previous codecs used, etc., may also be taken into consideration. Latency measurements may be used as a proxy for measuring available bandwidth. Based on these factors, a codec having appropriate attributes may be selected. Traditional rate shaping methods may be applied subsequent to the initial codec selection."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Codec selection based on offer","description":"Various of the disclosed embodiments improve the initial codec selection in a Voice Over Internet Protocol (VOIP) connection.
