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).<br>
<br>
Also, even not required by rfc, some UA implementations can be
broken.<br>
<br>
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.<br>
<br>

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.<br>

<div dir="ltr">Hello All. I have kamailio with
provider connection (trunk)<br>
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. <br>
<br>
This is my little dump for situation wherer I
hangup from internal number and BYE finished
successfully:<br>
