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?

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:

How can I force it to send the correct tag?
