Hi,
We are trying to make the integration with 3-rd party system, that's connected to the Genesys Cloud CX by SIP Trunk.
They sending to us some information in the SIP header in the X-User-to-User field
The 3rd party system would have to use the following values for the x-User-to-User header, as described in UUI data formats:
12345;encoding=ascii
or
3132333435;encoding=hex
If you do not specify the encoding parameters, it is assumed to be hex data I think.
As 12345 (X-user-to-user: 12345) is not a valid hex, your Call.UUIData is empty.
If you try with 3132333435 (X-user-to-user: 3132333435), it is a valid hex and your Call.UUIData should then be equal to 12345 (decoded hex).
