Hello,
I'm trying a new chunklet of config in loose_route(). I believe this came from
a documentation page somewhere, so I don't pretend to take credit for the
concept.
# Clean up dialog data if necessary
if ($DLG_status!=NULL && !validate_dialog()) {
xlog("L_INFO", "Unable to validate dialog,
fixing - $hdr(CSeq) on $ci\n");
fix_route_dialog();
}
I send the first batch of pseudo-production traffic through this config today
and I ended up with a metric ton of:
ERROR:dialog:dlg_validate_dialog: Check failed for route number 0.
req=[sip:<opensips-IP?;lr;ftag=23ddd50-0-13c4-1f179b-78884527-1f179b;did=45b.b972314],dlg=[sip:<opensips-IP>;lr=on;ftag=23ddd50-0-13c4-1f179b-78884527-1f179b;did=45b.b972314]
And, the xlogs from the above line:
Unable to validate dialog, fixing - 3 BYE on <callid>
It showed up on a number of BYEs and ACKs. My dialog module config is as
follows:
# ----- dialog params -----
modparam("dialog", "dlg_flag", 4)
modparam("dialog", "bye_on_timeout_flag", 4)
modparam("dialog", "default_timeout", 21600)
modparam("dialog|sst", "timeout_avp", "$avp(s:dialog_timeout)")
modparam("dialog", "dlg_extra_hdrs", "Hint: dialog expired\r\n")
modparam("dialog", "dlg_match_mode", 1) # 0 = DID_ONLY; 1 = DID first, SIP
second; 2 = SIP only
modparam("dialog", "db_url", "mysql://osuer:ospass@dbcluster/osdb")
modparam("dialog", "table_name", "dialog_1")
modparam("dialog", "db_mode", 1) # 1 = Realtime to DB; 2 = delayed; 3 = on
shutdown
modparam("dialog", "profiles_with_value", "711calls; 729calls; calls")
create_dialog() runs on all initial INVITEs.
Is this type of behavior anything close to normal? What might cause it? My
immediate fix is to simply comment out this portion of the config, but I'm
afraid I might be masking a larger issue. Any suggestions would be great.
Just had a thought as I was about to send this email. Perhaps this is because
by the time the BYE gets to this portion of the script, the dialog is already
torn down? Could it be that simple, just add "if !(is_method("BYE") ||
is_method("ACK"))" to the top line of this config portion?
