Alex,
Are you sure this is not a bug with the other endpoint (the other side
of the call)? The end-to-end ACK for the 200 OK would have to originate
from it and Kamailio would merely be relaying it. Is it possible that
it is in fact that UA which is ignoring the To tag in the 200 OK from
1.1.1.1?

Hi,
I made a simple SIP test call. The end point reply to kamailio with 180,
200 messages. The end point includes "tag=1_1555_t58918_125k" in TO
field of these messages. However, kamailio reply with ACK message that
includes a random tag (tag=5f08ae5f) in TO field. This tag is not the
same as the one sent by the end point:
1.1.1.1 end-point ip address
2.2.2.2 kamailio ip address

How can I force it to send the correct tag?
