And also, forget to say: it happens after 200ok from carrier... I mean, the first one transaction kamailio uac <=> carrier is ok. invite => <= 407 invite => <=183 <=180
and then 200Ok when PSTN side answer on call.
<= 200 ok => wrong ACK (with initial to/from, which they was before uac_replace)

Thanks! Rly appreciate your help!
So, I can try to execute the same branch_route for ACK method? I have this branch route:
branch_route[MODIFY]{ uac_replace_from("","$avp(from)"); uac_replace_to($avp(to)); }
Now I execute this when request goes from asterisk through kamailio to carriers...
Should I execute this branch route into ACK method from asterisk too?

Hello Zhan,
possible reasons:
- the ACK is not routed through your proxy (missing record-route for the
INVITE)
- the user agent mangles the Route header, therefore the uac module can't
does it work correctly (look to the kamailio error logs if you spot something)
Have a look to your SIP e.g. with "ngrep -qt -d any -W byline port 5060" on your proxy.
Cheers,

Hello, Thanks for reply! Yes I execute uac_replace_to/from in branch_route in INVITE method... But it doesn't work for ACK method...

Hello Zhan,
have a look to the "uac" module, there are functions to rewrite the From and To header for passing messages. It works together with the rr module.

Hello! Please, is it possible to change from/to headers in ACK message to provider? this is exactly our case, please, look it when u get a chance. http://sip-router.1086192.n5.nabble.com/Wrong-ACK-to-Provider-td130050.html#...
