device B ends the call because it doesn't receive the ACK for the 200. Are you 
sure such request is sent to the right port/ip?
Do you have same issue with UDP?

Call is termitated also with UDP. Why does it work fine with revision 832?

I accept log with r832.

Do not obfuscate IP addresses using same pattern *.*.*.*.
Each address must be replaced by it's own pattern (x.x.x.x, y.y.y.y, 
z.z.z.z...) otherwise, we cannot understand what's going on.

*.*.*.* is server IP.

Оne clarification: we have server behind NAT.

Looks like the ACK is never received by your server as it continue to send the 
200 OK.
Tried with Xlite, Bria and Linphone using your network and got same issue.
The problem looks to be the "Record-Route" in the responses as it says to send 
the ACK to x.x.7.24 which is most likely not valid (or no one listening).

Is there an explanation why revision 832 worked with the same server settings?
This may give us some clues.

There was a bug in these revisions as we always send back the response to the 
proxy address instead of the first Route.

I idded in kamailio config:

 if (!is_method("REGISTER|MESSAGE")) 
 { 
       record_route_preset("x.x.x.x"); //external server address
 }

The call is not terminated now. But the route is lost after re-INVITE.
