<div>When the user has two devices answering the phone at the
same time, I expect the first device to answer the call and
the second device to be cancelled.<br>
<br>
The current opensips will indeed cancel the second call, but
the first call will have no sound, and the call will be
disconnected after a few seconds.<br>
<br>
I found that opensips sends all 200 Ok (SDP) to the caller,
and I expect that the second 200 Ok (SDP) should not be sent
to the caller.<br>
<br>
</div>
<div>I try to block the second 200 Ok(SDP) in onreply_route,
like this.</div>
<div><br>
onreply_route[handle_nat] {<br>
if (t_check_status("200")) {<br>
# t_cancel_branch(); No effect<br>
# drop(); No effect<br>
#exit;<br>
}<br>
}<br>
<br>
But this seems to have no effect.<br>
<br>
Is there a way to block the second 200 Ok (SDP) in
onreply_route?<br>
<br>
Or is there any other way to handle concurrent answering
calls?<br>
<br>
I use opensips 3.1.5 and rtpproxy 2.2.0.</div>
