Hello, I would like to send a MIME(binary data) content embedded in an INVITE request. I would also like to send a MIME (binary data) embedded in an ACK method (after receiving an INVITE request). In which concerns the INVITE method there are two functions: pjsua_call_make_call and pjsua_call_im_send. 1.) In pjsua_call_make_call I would like to know if I could use the msg_data parameter for my purpose. 2.) I would like to know what is the purspose of pjsua_call_im_send function. I read that it sends an INVITE method along with an instant message, but requires a call id as input, and this call id can be obtained only after the call is established, as far as I know. 3.) In which concerns the ACK method I would like to know if I could use pjsua_call_answer function (by setting the msg_data parameter) for my purpose. Thank you, Bogdan Chifor -------------- next part -------------- An HTML attachment was scrubbed...
