Hello colleagues.
I'm starting to use Kamailio for educational purposes, as an IMS test zone. Registration of subscribers, calls go successfully, but the following errors are constantly pouring into the log:

Apparently they don’t carry anything critical, but they clog the log, natively I can’t understand the meaning of the errors.
Please tell me what they mean and how to eliminate their cause? If necessary, I will provide the pcscf config.
