<tt>Hi Ben,<br>
<br>
<tt>OK, my experiment<tt> with 2.4 :<br>
<br>
<tt>* Ha<tt>ve a call <tt>up between two endpoints</tt></tt></tt><br>
<tt>* kill the <tt>end points, w<tt>ithout allowing them to
send any BYE or so<br>
<tt>* do an<tt> dlg_end_dl<tt>g from opensips proxy<br>
<br>
<tt>What I <tt>got:<br>
<tt><tt>1) the <tt>2 BYE requests are send
out, b<tt>oth visiting the local route
(where the failure route is armed)<br>
<tt>2) the first BYE ends with <tt>internal
<tt>408 timeout (based on <tt>re<tt>transmissions),
failure route is triggered
(where an ex<tt>tra <tt>acc
var is set), the dialog
tran<tt>sits into
TERMINATED state, the
acc CDR is ge<tt>nerated
(<tt>holding the
value set in
failure route)<br>
<tt>3) <tt>the
seco<tt>nd BYE
ends also w<tt>ith
408 timeout,
the fai<tt>lure
route is al<tt>so<tt>
trigger<tt>ed
(<tt>I can see
the xlog()),
but as the
dialog is <tt>TERMINATED,
th<tt>ere is
no impact on
the acc<tt>
level.<br>

<tt>The Dialog is not terminated (as status) with the first

the status is). Even if both caller and callee BYE will
turn into 408 or 481, the first to fire will terminate the

that. However, this only makes sense in the case where there
is a successful response prior to the error response. As I
noted I have seen this occur when both parties reply to the
BYE with a 481 response. If the Dialog and ACC modules were

<p>I think you should take care of this on your gateway. For
example, using freeswitch or asterisk, you can check for
rtps, and when the other end stops sending rtps for 30
seconds (configurable) it will tear down the call
properly.
<o:p></o:p></p>
<p>Unless you're using a rtp-proxy with opensips which can
do this (most can), that's the way to do this. Anything
else is just duct-taping.<o:p></o:p></p>
<p>My opinion after 20 years on voip.<o:p></o:p></p>
<p>Hope that helps.<o:p></o:p></p>
