I have the lastest MWO app (28 oct 2021) and use it with IFS Cloud 21R1.
I can make calls and hear the ringing sound on the mobile device but I cannot hear the person in the backoffice. The other way round, the person in the office can hear the mobile engineer.
Is this expected behavior or should there be sound (which I expect when I look at the Cimcorp demo video).
Does anyone have any suggestions besides checking if all volume controls are on ;-)
