Maybe there is a parallel forking and one branch gets timed out (in
this case 408 is selected against 486). How many INVITE requests do
you see being sent out? Or you can eventually make the sip trace
available for viewing on this mailing list or some web site/pastebin
out there.<br>

<div>However when endpoint replies with 486 BUSY I can't see
that on FS, Kamailio just sends 408 REQ TERM after some amount
of time<br>

<div>I need to relay 486/408/... other failure

is recommended just to exit failure_route, but
that didn't work for me. I need that to let
Freeswitch know which cause has ended the call.
Now Kamailio just sends ACK to endpoint on
receiving 486 BUSY. Would you kindly tell me how
to achieve that?<br>
