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,
Daniel

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,
Daniel

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:
