Hi Pavel,

OK, I will ask Liviu to take a deeper look into this, thanks for the report.

Thanks for your answer I suppose there is some little mistake in the code of mid_registrar due to this error easylly reproducing on the new opensips installation. Conditions are simple: centos 7 or debian 10, opensips 3.2 ver, use mid_registrar (mode=2 or 1) and registrar in the same script. For example for REGISTER with tU like 1000 we will make mid_registrar_save and for 20000 we will do save().
In case of save() we will get those errors in logs.

I have created an issue(https://github.com/OpenSIPS/opensips/issues/2716 <https://github.com/OpenSIPS/opensips/issues/2716>) on github about that.

    Hi Alexey,

    What the errors say is that mid-registrar, upon deleting/expiring
    a registered AOR, it is not able to push forward the un-register
    to the main registrar. This happens as some internal key (attached
    to the AOR) is not found by the mid-registrar.

    Not sure how this may be related to the changing of the IPs, but I
    guess this issue went away after some time, right? if not, you may
    stop opensips mid-registrar, purge the "location" table (or how
    you named it) and start opensips back. This will flush all the
    pending (potential bogus records) and give you a fresh start. Note
    that your device will have to re-register in order to have the
    calling working again.

    Regards,

    Bogdan-Andrei Iancu

    Hi list.
    What do these errors mean?
    This started after migrating the virtual machine and changing IP
    addresses.
    Everything else remain unchanged.
    Version 3.2.2
    ERROR:mid_registrar:unregister_record: 'from' key not found,
    skipping De-REGISTER
