In src/modules/rtpengine/rtpengine.c:
> + if(sess->branch != RTPENGINE_ALL_BRANCHES)
+ bencode_dictionary_add_str(dict, "via-branch", viabranch);
+ if(to_tag && to_tag->len)
+ bencode_dictionary_add_str(dict, "to-tag", to_tag);
+ if(copy_flags & RTP_COPY_MODE_SIPREC) {
+ list = bencode_list(&bencbuf);
+ bencode_dictionary_add(dict, "flags", list);
+ bencode_list_add_string(list, "all");
+ bencode_list_add_string(list, "siprec");
+ } else if((copy_flags & RTP_COPY_LEG_BOTH) == RTP_COPY_LEG_BOTH) {
+ list = bencode_list(&bencbuf);
+ bencode_list_add_string(list, "all");
+ } else if(copy_flags & RTP_COPY_LEG_CALLER && sess->from_tag) {
+ bencode_dictionary_add_str(dict, "from-tag", sess->from_tag);
+ } else if(sess->to_tag) {
+ bencode_dictionary_add_str(dict, "from-tag", sess->to_tag);
If you mean that it should be like:
} else if(sess->to_tag) {
bencode_dictionary_add_str(dict, "to-tag", sess->to_tag);
I don't think so. In the case that any of RTP_COPY_LEG_BOTH, RTP_COPY_MODE_SIPREC and RTP_COPY_LEG_CALLER flags are not in copy_flags, it means that it is copying rtp stream of the callee. The 'from-tag' for RTPEngine indicates which participant stream must be copied and here we want to copy callee's stream which is in sess->to_tag variable.
'to-tag' for RTPEngine means where to send copied rtp streams.
