Source notes citing this source

Genesys advises encoding UUI as ASCII rather than hex when the data uses extended ASCII characters 128-255, because hex causes problems with those characters. in context
Genesys Cloud also accepts a User-to-User variant where the protocol discriminator is given in a separate pd parameter, and in that case it does not remove the first data octet. in context
For REFER-based transfers Genesys Cloud carries UUI as an escaped User-to-User header parameter inside the Refer-To URI. in context
With the standard User-to-User header type Genesys Cloud treats the first octet as the protocol discriminator and removes it before exposing the data. in context
Genesys documents x-User-To-User as an AudioCodes proprietary header that carries only the data, without the protocol discriminator or the standard purpose and content parameters, encoded as hex or ascii. in context
