Hi Gaurav, thank you very much for your prompt response. I can indeed see the "on_state" callback-stub inside of struct "pj_turn_sock_cb". However, I do not see, how I can gain access to that "pj_turn_sock_cb" structure, in a situation, where TURN is configured through "pjsua_media_config" and the allocation is initiated and conducted under the control (and "hood") of pjsua_init(). I am probably overlooking something ...? - Any hint is appreciated.
