is there a means to check if reply to t_relay()ed request is
retransmission? there is t_is_retr_async_reply(), but that does not
apply to regular transactions.
i would like to avoid double calling of rtpengine_answer().

t_check_trans() will consume retransmissions.

i don't get that impression:
* For a SIP Reply it returns true if the reply belongs to an existing
transaction and false otherwise.
if i get two 200 oks to the same invite, both of them belong to an
existing transaction. the thing i want to know is if reply is the first
reply or a retransmission of the reply.

I don't think there is a built-in for that. I ended up storing the Via branch
parameter of the reply in a htable.

Indeed it is no function in config to
detect if a reply was
retransmitted. Alex's suggestions could be a way.
But, iirc, some of the retransmitted replies have to be just forwarded
and for them, the rtp proxy needs to be engaged again in order to update
the sdp. The rtpproxy (and expect the same from rtpengine) handles it
properly, because it detects existing session by call id and tags.
Cheers,

thanks for your reply. i'll then just
call rtpengine_answer again and
hope that it will notice that it is a recall.
