Alex,
We are using a pretty close to default configuration.
Below is the routing blocks above and below where async_route is
located(async_route actually is inside my route[REGISTRAR] block.
# Handle requests within SIP dialogs
route[WITHINDLG] {
if (has_totag()) {
# sequential request withing a dialog should
# take the path determined by record-routing
if (loose_route()) {
route(DLGURI);
if (is_method("BYE")) {
setflag(FLT_ACC); # do accounting ...
setflag(FLT_ACCFAILED); # ... even if
the transaction fails
}
else if ( is_method("ACK") ) {
# ACK is forwarded statelessy
route(NATMANAGE);
}
else if ( is_method("NOTIFY") ) {
# Add Record-Route for in-dialog NOTIFY
as per RFC 6665.
record_route();
}
route(RELAY);
} else {
if (is_method("SUBSCRIBE") && uri == myself) {
# in-dialog subscribe requests
route(PRESENCE);
exit;
}
if ( is_method("ACK") ) {
if ( t_check_trans() ) {
# no loose-route, but stateful
ACK;
# must be an ACK after a 487
# or e.g. 404 from upstream
server
route(RELAY);
exit;
} else {
# ACK without matching
transaction ... ignore and discard
exit;
}
}
xlog("SCRIPT: $TF Call to $rU but not currently
in usrloc db SIP/404\n");
sl_send_reply("404","Not here");
}
exit;
}
}
# Event Route for Expired Contact
event_route[usrloc:contact-expired] {
xlog("expired contact for $ulc(exp=>aor)\n");
}
# Handle SIP registrations
route[REGISTRAR] {
if (is_method("REGISTER"))
{
if(isflagset(FLT_NATS))
{
setbflag(FLB_NATB);
# uncomment next line to do SIP NAT pinging
##setbflag(FLB_NATSIPPING);
}
xlog("SCRIPT: $TF $au registered to usrloc db from $si
from useragent type of $ua\n");
if (!save("location", "0x4"))
sl_reply_error();
async_route("PUSHJOIN", "2");
exit;
}
}
# USER location service
route[LOCATION] {
#!ifdef WITH_SPEEDDIAL
# search for short dialing - 2-digit extension
if($rU=~"^[0-9][0-9]$")
if(sd_lookup("speed_dial"))
route(SIPOUT);
#!endif
#!ifdef WITH_ALIASDB
# search in DB-based aliases
if(alias_db_lookup("dbaliases"))
route(SIPOUT);
#!endif
$avp(oexten) = $rU;
if (!lookup("location")) {
$var(rc) = $rc;
route(TOVOICEMAIL);
t_newtran();
switch ($var(rc)) {
case -1:
case -3:
xlog("SCRIPT: $TF Call to $rU but not
currently in usrloc db SIP/404\n");
send_reply("404", "Not Found");
exit;
case -2:
send_reply("405", "Method Not
Allowed");
exit;
}
}
# when routing via usrloc, log the missed calls also
if (is_method("INVITE"))
{
setflag(FLT_ACCMISSED);
}
route(RELAY);
exit;
}
Thanks!

Aaron,
Where is the call to async_route() situated in the core request route?
That is, what is called before and after the async_route?

We just updated our development environment from 4.2.2
to 4.2.5 and
started noticing the server sending a 500 I'm terribly sorry, server
error occurred (1/TM) error back as soon as the async_route block gets
called. I have removed everything from our async
route other than an
xlog statement trying to determine if something in that route block
was causing the 500 to occur. It still happens even with only the
xlog.
If the async_route is not in the config, then the server does not send
the 500 response.
We rolled back to 4.2.2 and the problem no longer occurs.
I have attached a sip trace of the messages. I believe the relevant
parts of our config are below, please let me know if you need more
from the config however.
Any ideas?
async_route("PUSHJOIN", "2");
--------------------------
route[PUSHJOIN] {
xlog("L_INFO", "Does it get here?\n");
exit;
}
Thanks in Advance,
Aaron
