Hallo, I want to implement a SIP application that can establish Video-Calls. But this device has only a camera, no display. Currently I started with PJSIPUA2. Pure audio calls are working fine but When I establish a video call, I want to set the direction for video immediately to sendonly. So the SDP for an INVITE request and for an INVITE OK response shall always be "sendonly". Is there a possibility to set the direction to PJMEDIA_DIR_ENCODING as default (not PJMEDIA_DIR_ENCODING_DECODING)? Or is there another possibility to achive this Furthermore I have no render device. What value must I set to tell the stack that I have no render device and I don't want to use one? Thanks, Sandra
