@sergey-safarov this doesn't look like a kamailio issue. you may need to capture amqp packets from/to kamailio andalso look into kamailio logs. the items you're reporting as `unexpected` seem like an `expectation from user` rather than `unexpected because current state is ...`. what i mean is, the attached pcap is not enough to do an assessement of a possible issue that doesn't occur with other deployments of kamailio with kazoo.
