So, what you're saying is that the ACK (response to 200 OK from
endpoint) from the softswitch comes with a To tag of 1_1555_t58918_125k
to Kamailio, but the ACK that Kamailio sends out to the endpoint has an
altered To tag? Have you checked?

Alex,
The other end-point is a softswitch. I made a direct test call excluding
kamailio. Everything was fine, calls go thru with correct tag value.

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?

How can I force it to send the correct tag?
