Yes, that is an accurate conclusion, and there is no harm in it. 

Hopefully, dialog timeouts are a relatively aberrant event. The whole spoof-BYE implementation is a hack, outside the prescribed behaviour for SIP proxies, which cannot normally originate any requests. Abnormal events are often accompanied by abnormal errors.

Ok I understand, the warning is generated in bye_reply_cb() which I guess is called when the 200 is received for the BYE, and in this case, there are two 200 (one for each BYE).

 

The function send_bye() [dlg_req_within.c:325] is called twice: once for the caller and another time for the callee. I also see the bye_reply_cb callback is registered for each BYE sent, therefore this callback is called twice.

 

Therefore, I conclude this warning will appear every time a dialog timeout occurs?

It looks like it is a real issue since CDRs are not generated on dialog timeout.

 

If the dialog is not in the timer list, does that mean the DLGCB_EXPIRED callbacks are not called?

The log message is not related. It pure about trying to see if the dialog is still in the timer list and remove it, failing because it was already removed -- it will not get to that state if it was not in the timer already.

Hi,

 

I get the following warning when a dialog timeout occurs:

 

kamailio[18889]: WARNING: dialog [dlg_req_within.c:214]: bye_reply_cb(): inconsitent dlg timer data on dlg 0x7f422986e448 [3547:6673] with clid 'mycvJWgmbmOSD5XQrcStKAKoTfW12XeR' and tags 'C5mlsaZCdTmybNSYgvWr75MBxWa5hVyA' 'L1ZzszpZ1MYO6qlQQ3FYYRWQYtF4F75r'

 

Am I doing something wrong?

do you get it always when a dialog times out?

The warning is for the case when the dialog is no longer on timer list, which can happen when there are two BYEs crossing through. The situation is harmless, perhaps the log message has to be done as info not warning.

Cheers,
Daniel
