I think this is a side effect of misrouted message in a BYE, where kamailio reports that the dialog expired due to timeout. This does not point at cause of the issue, but is rather a symptom that something went unexpected ways. For example, it could be logged due to dialog module noack_timeout (1 minute by default) since the message appears in roughly one minute plus some seconds after BYE is received. In any case, this is a passive message related to active dialogs tracking in kamailio.
Marcos wrote that the issue occurs with one specific equipment type, which makes me think this is an endpoint issue, e.g. end device is sending incorrect contact or record-route in the 200 ok message. I have encountered some devices in the past that send server's FQDN rather that its own public IP In contact header. As a result, the message will be looped and/or dropped inside kamailio. Those are some of the points to check, but the file I have received from Marcos in private was corrupted
- probably stopped in the middle of capture (wireshark says "The capture file appears to be damaged or corrupt.
(pcap: File has 1634614131-byte packet, bigger than maximum of 262144)") so I have not managed to check this and also didn't have time to follow-up.
Please send a new file if you still need help on this Marcos.
