Hi Olle and Nina, for some time I worry about the same issue and it's still not solved :-( My app uses pysua and i asked already and wait for reply on that: What (call) status is required on call-out to read the DTMF? In my python app, it is set to 200. If i do not set it to 200, there is no voice at the other side although pjsua sends audio signals. However, when doing so (status 200), i miss any dtmf signals. Does it work with You when trying pjsua?
