Thanks. It works well. But retransmission timeout problem still exists... I
suppose it was not wrong ACK problem.
But many thanks!!

Hello Zhan,
you need to also execute it also for the ACK request. I just tested it on
a test setup, I just placed it here for a quick test (refer to the default
cfg):
...
uac_replace_from("","sip:batman@gotham.org"
<sip:batman@gotham.org>);
uac_replace_to("","sip:robin@gotham.org"
<sip:robin@gotham.org>);
# handle requests within SIP dialogs
route(WITHINDLG);
...
Works just fine:
2019/08/04 18:43:21.727990 XXX.XXX.178.27:5060 -> XXX.XXX.167.107:5060

Hello,
Thanks, I will try!
Should I add this into the same route?
I execute uac_replace into route[FROMASTERISK] if method is invite.

Hello Zhan,
I obvious don't know your cfg details. But I would try to just call the
uac_replace_from/ .._to in the main request_route and see if it works at
all in your routing logic. Also add some xlog messages to see that it is
executed. You can also output with $rm the SIP request method, with $ru the
request URI etc.. (see the cookbook for pseudo-variables for all that are
available).
Cheers,
Henning

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...
