Be sure you checked the two types of ack requests: hop-by-hop (for negative replies, where the contact is not important at all) and end-to-end (which is for a 200ok).
Also, even not required by rfc, some UA implementations can be broken.
Anyhow, if you tested and doesn't help, I would try to use record_route() for ACK. If that doesn't help, you will need the help of the provider to tell you why it doesn't send the BYE.
Cheers,

RFC not specified Contack header at ACK... So anyway I already tried it yesterday)) Unsuccessfull...

Hello,
I noticed that the ACK is missing the Contact header -- not sure if specs mention anything about being mandatory or not, but you can try to get the contact there.
Cheers,

Hello All. I have kamailio with provider connection (trunk)
When I call to external number through my provider call extablished Ok. But when i try hangup call from external number no BYE sended to me. When I hangup call from my kamailio (internal num) I send by to exteral number and it respond me Ok so session if fully complete. I guess that BYE from external number not recieves to me because I have wrong routing header fields at my INVITe or ACK messages, but can not find any information what what header must recieve info to external number where send BYE at hangup or thomething like this.
This is my little dump for situation wherer I hangup from internal number and BYE finished successfully:
