 The Azure Communication Services (ACS) WebJS SDK provides developers to include custom contextual data (included as a header on the calling object) when directing and routing calls from one person to another.  This information, also known as User-to-User Information (UUI) data or call control UUI data, is a small piece of data inserted by an application initiating the call. The UUI data is opaque to end users making a call.
