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 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.

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? пт, 2 авг. 2019 г. в 20:11, Henning Westerholt <hw(a)skalatan.de>de>:

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) пт, 2 авг. 2019 г. в 20:27, Zhan Bazarov <chiefkeeft(a)gmail.com>om>:

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 Am 02.08.19 um 19:27 schrieb Zhan Bazarov: Thanks! Rly appreciate your help!

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.

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 Am 03.08.19 um 22:40 schrieb Zhan Bazarov: Hello, It didn’t make any sense, unfortunately...

Thanks. It works well. But retransmission timeout problem still exists... I suppose it was not wrong ACK problem. But many thanks!! вс, 4 авг. 2019 г. в 19:46, Henning Westerholt <hw(a)skalatan.de>de>:

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); ...

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 Am 03.08.19 um 22:40 schrieb Zhan Bazarov: Hello, It didn’t make any sense, unfortunately...

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 Am 02.08.19 um 19:27 schrieb Zhan Bazarov: Thanks! Rly appreciate your help!

As a note for the mail archives - it should work if you just call it on the initial INVITE if the requests are routed properly through kamailio. The uac module will then use callbacks to rewrite replies and following in-dialog requests.
