Hi, In our project we need to handle inbound INFO requests with asynchronous postponed responses. As far as I understand the correct SIP handling is to send 100Trying, process the request, and finally send the final response, e.g. 200Ok. However, pjsip_endpt_create_response method requires initial pjsip_rx_data, and there are complications to store and handle it. Could you please advise any straight-forward way like pjsip_inv_answer method? Or pjsip_rx_data caching is a proper way to implement such functionality?
