Dedicated Instance integrations with Webex Contact Center require a codec list ordered G.711 U-Law first, then G.711 A-Law, then OPUS, built from Factory Default Lossy and assigned across CTI, endpoints and SIP trunk device pool regions, and this must be done only for the Webex Contact Center integrations.
