Hello,
It didn’t make any sense, unfortunately...
In additional - kamailio relay right 200 to Asterisk, and asterisk send ACK
with wrong from/to(initial values like it was before uac_replace) and then
kamailio doesn’t change it to right from/to values.
Any idea, please.

Hello Zhan,
there is no need to execute a branch_route on an ACK. The ACK should be
just routed "normally" through Kamailio. Have a look to the default cfg,
for example. The ACK in a normal call setup is just a "normal" request.
Cheers,
Henning

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,
Henning

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.
Cheers,
