Correct me if I'm wrong, but not all within-dialogs are 'calls', for e.g. NOTIFY with a preset Route after SUBSCRIBE, wondering how dlg_manage() would treat those, would it count them as 'calls'?

Not to mention that docs mention "dlg_manage() - this makes sense only for initial requests)

Please put dlg_manage immediately after loose_route condition, e.g.

if (loose_route) {
    dlg_manage();
...
}

There is no harm in calling it for every SIP method (not just BYE or ACK) within dialog. It will help for re-invites (call hold / unhold events) etc. from same buggy UAs as well.

Thank you.

Hello,

I've tried what you recommended, but without success so far.

This is the configuration block:

if (!has_totag()) return;

if (is_method("ACK")) {
   dlg_manage();
  }

  if (loose_route()) {
    if (is_method("BYE")) {
      dlg_manage();
      setflag(FLAG_ACC);
      setflag(FLAG_ACCMISSED);
      $dlg_var(billsec) = $DLG_lifetime;
    }
    route(RELAY);
    exit;
  };

  if (is_method("ACK") ) {
    if ( t_check_trans() ) {
      route(RELAY);
      exit;
    } else {
      sl_send_reply("606", "Not Acceptable");
      exit;
    }
  }

Here is the sip trace:

And that's the error I'm getting in the Kamailio log file:

WARNING: dialog [dlg_handlers.c:1652]: dlg_ontimeout(): dlg timeout - callid: ' 0555141d7d3hsag78sgce830391f9348@10.1.50.240:5060' tags: 'as52c10007' 'Uv7HS0jX65ctF' ostate: 3

Any other ideas?

Hello,

I see the in-dialog ACK in the trace, try with dlg_manage() explicitly used for it.

The warning messages are not when processing the ack, but on dialog timeout, if you do not get some other errors like 90-120 seconds before, when the ack was routed, then it was no processing error for it.

Cheers,
Daniel

Hello,

In the Kamailio logs I can see only those errors:

WARNING: dialog [dlg_handlers.c:1652]: dlg_ontimeout(): dlg timeout - callid: '45b0130e14a692b95134696d2fc5f2a9' tags: 'as31fb1118' '12UDcK9S8630r' ostate: 3
WARNING: acc [acc_cdr.c:230]: db_write_cdr(): fallback to dlg_only search because of message doesn't exist

Here you can see the full sip trace:

The First Invite it's from the Asterisk server (192.168.0.140), and the second one - it's from Kamailio (192.168.1.16), 192.168.2.0/24 - it's an ISP. What 's strange for me here is that Kamailio it's still adding rr_param to the RR Header even if it's disabled in the module configuration, why would that be?

This is the module configuration:
modparam("dialog", "enable_stats", 1)
modparam("dialog", "rr_param", "did")
modparam("dialog", "dlg_match_mode", 2)
modparam("dialog", "default_timeout", 10800)
modparam("dialog", "early_timeout", 180)
modparam("dialog", "noack_timeout", 90)
modparam("dialog", "track_cseq_updates", 1)
modparam("dialog", "dlg_extra_hdrs", "Hint: Inactivity Timeout\r\n")
modparam("dialog", "detect_spirals", 1)
modparam("dialog", "db_mode", 1)

I will try to run dlg_manage for ACK within the dialog and see if it works.
Thank you.

Hello,

that confirms my guessing -- the ack was not handled in the dialog context, the state 3 is defined inside dlg_hash.h by:

#define DLG_STATE_CONFIRMED_NA 3 /*!< confirmed dialog without a ACK yet */

Do you see any error messages in the logs when handling the ACK in the config? Did you grab the pcap with sip traffic for such a call?

Try also to explicitly execute dlg_manage() for ACK within dialog.

Cheers,
Daniel

I re-compiled Kamailio from the Master branch and I'm getting the old state: 3

Hello,

this sounds like the ACK is  not matched for dialog processing and the early_timeout is firing. I just pushed a commit to dialog module to print the old state when the timeout callback function is executed, maybe you can test with it -- it is in branch 5.3:

  - https://github.com/kamailio/kamailio/commit/ff2f8c4e63b4fefa7dc5b10835505c3c4ae84388

Otherwise, maybe call dlg_manage() for ACK, although the loose_route() callback should be executed and ACK handled for dialog processing.

Cheers,
Daniel

Hello,

I'm trying to get CDR working in Kamailio by using the acc and dialog modules. Everything seemed to be working fine - until i noticed that for some of the calls the call duration is 0, even if that call has been successfully established and duration was for about a few minutes. In the Kamailio logs I'm getting such errors:

WARNING: dialog [dlg_handlers.c:1649]: dlg_ontimeout(): timeout for dlg with CallID '304bad142b50bb3a7a117816439ea3d5' and tags 'as3adde5c7' '7d28152f-e0e3-4bcf-9d5c-21c3723b95c5'
WARNING: acc [acc_cdr.c:230]: db_write_cdr(): fallback to dlg_only search because of message doesn't exist.

This error I'm getting at about 2 min after the ACK message for 200 OK. I'm not sure that this is related to the dialog timeout, but below you can see the related configuration for the dialog module:

modparam("dialog", "default_timeout", 10800) # 3 hours
modparam("dialog", "early_timeout", 180)
modparam("dialog", "noack_timeout", 90)

Unfortunately, I'm not able to reproduce this issue, as that's happening randomly and just a few times per day. On the SIP Level i didn't notice any strange issues.

Any ideas why is that happening?
Thank you.
