rtpengine. Unknown codecs

After upgrading minor version Debian 12, Kamailio and rtpengine stopped proxying media traffic. (The combination works exclusively as a SIP proxy.)
Systemctl status kamailio and rtpengine is ok (enabled, activating).
No configuration errors.

Call flow.
PBX --> Kamailio\rtpengine ---> Video conference system. Internal audio calls only. 

When calling, there's silence and the connection hangs up.

Found some strange rtpengine logs.
 Unknown codecs? How is it?-)
