When 118 send BYE to Server.<br>
But Server tell 118 " Not Here".<br>
<br>
It's my config for BYE<br>
<br>
if (has_totag()) {<br>
# sequential request withing a dialog should<br>
# take the path determined by record-routing<br>
if (loose_route()) {<br>
if (is_method("BYE")) {<br>
setflag(1); # do accounting ...<br>
setflag(3); # ... even if the transaction fails<br>
} else if (is_method("INVITE")) {<br>
# even if in most of the cases is useless, do RR for<br>
# re-INVITEs alos, as some buggy clients do change route set<br>
# during the dialog.<br>
record_route();<br>
}<br>
# route it out to whatever destination was set by loose_route()<br>
# in $du (destination URI).<br>
route(1);<br>
} else {<br>
/* uncomment the following lines if you want to enable presence */<br>
if (is_method("SUBSCRIBE") && $rd == "192.168.20.118") {<br>
# in-dialog subscribe requests<br>
route(presence_handling);<br>
exit;<br>
}<br>
if ( is_method("ACK") ) {<br>
if ( t_check_trans() ) {<br>
# non loose-route, but stateful ACK; must be an ACK after<br>
# a 487 or e.g. 404 from upstream server<br>
t_relay();<br>
exit;<br>
} else {<br>
# ACK without matching transaction -><br>
# ignore and discard<br>
exit;<br>
}<br>
}<br>
sl_send_reply("404","Not here");<br>
}<br>
exit;<br>
}<br>
<br>
Why is Not here??<br>
Can everyone help me? Thanks<br>
Nick<br>
