Hi Im using pjsip on the pjsua level. I need to get access to one of the headers in the incoming INVITE message. I have successfully parsed the event sent to "on_call_status_changed" for other messages like when I wanted to see the SDP in a 200 OK. The problem for me is that the incoming INVITE does not seem to be reported at all in "on_call_status_changed". There is a notification PJSIP_INV_STATE_INCOMING but that is sent after pjsip sends the 100 Trying and that is the message contained inside the pjsip_event. I need to access the INVITE that triggered the transmission of this 100 Trying message. So my questions are: 1. Is there a way to access the last RX message when receiving the PJSIP_INV_STATE_INCOMING notification. 2. Is there perhaps another/better way to achive this. I know I can see all incoming messages in on_rx_request but then I face a problem with connecting the incoming message in on_rx_request with the callback in "on_call_status_changed". If possible I would like to solve it through the pjsua interface. Thanks Johan
