Kamailio 5.4 used.
On dialogues calls, I noticed this happening on the second re-invite to refresh the session from the B side.
dlg_onroute(): unable to find dialog for INVITE with route param 'df9.da75' [2557:22445] and call-id '14148a68-f1b2-485d-b5a2-f9dd7773d2c0'
The did df9.da75 is identical to the one in the route-header on the first re-invite from the B side, before this one. No CDR was (yet) generated, and the dialogues is still present and on-going according to the database:
CallID [14148a68-f1b2-485d-b5a2-f9dd7773d2c0] H-Entry: 2557 H-ID: 22445
But most probably not in memory as kamcmd dlg.stat_active shows zero (this is on a development node, so no other calls running).
There are no sip messages that end the call in between those two re-invites. I see no session timeouts or similar in the logs.
Any hint what could cause Kamailio not to find the corresponding dialogue on this re-invite?
