hi
I found point where sdp message is creating.. is it in
endpoint.c source file and method "pjmedia_endpt_create_sdp"
here is code which add "sendrecv" attribute to SDP message:
/* Add sendrecv attribute. */
attr = PJ_POOL_ZALLOC_T(pool, pjmedia_sdp_attr);
attr->name = STR_SENDRECV;
m->attr[m->attr_count++] = attr;
as you see attribute "sendrecv" is still added. No condition if add
"sendonly", recvonly" or "sendrecv" attribute should be added :(
Maybe exist some callback which can overwrite? But i can't found anything...
..maybe call pjsua_call_set_hold() will be only solution :)
