In the ACC modules' database table (acc) in Kamailio sometimes from_tag, to_tag and callid of an INVITE and corresponding BYE completely match. But sometimes from_tag in INVITE is to_tag of BYE and to_tag of BYE will become from_tag of INVITE. Why this happens? Is this normal? Regards

hi, it means BYE was generated by called party, so the To and From URIs and tags have been swapped. 2015-12-20 11:52 GMT+03:00 Gholamreza Sabery <gr.sabery(a)gmail.com>om>:

Thank you Dmitri. But It seems that it should not work this way. Here: https://supportforums.cisco.com/document/113271/understanding-sip-traces it is written : Note that the To and From header fields are not reversed in the response message as one might expect them to be. This is because the To and From header fields in SIP are defined to indicate the direction of the request, not the direction of the message. Any ideas?

To add: if you use rr module with append from tag enabled, then acc module can detect the direction of BYE and change From/To tag when writing the record to database to match the values for INVITE -- look at the parameters for rr and acc modules.
