Hello Stefan,

I digged further into this issue and looked to the protocol format in utils/pdbt/docs/
network_protocol.txt.

One strange thing I noticed:

Kamailio sends a request in version 1 out, this is the default since 2015 or so.

Kamailio recieves a reply in version 0, it should be version 1 as well.

Do you query with the Kamailio 5.1.x to the pdbt server in version 4.x? If yes then I 
suspect this is the problem.

The version change in pdbt was done after the release of the 4.3 branch.

Best regards
