Source notes citing this source

• If incoming UUI carries no encoding parameter, Genesys Cloud assumes hex encoding. in context
• For inbound calls Genesys Cloud looks first for a User-To-User header and only if it is absent for an x-User-To-User header; if both are present it uses User-To-User. in context
• Genesys says UUI can persist to a PBX or SBC reached over a BYOC Cloud or BYOC Premises trunk with UUI enabled, but is unlikely to persist if the far end is reached through the PSTN. in context
