<p>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.<br>

<p>Hello Zhan,</p>
<p>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).</p>

<p>Hello Zhan,</p>
<p>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.<br>
</p>

Rly appreciate your help! <br>

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

<p>Hello Zhan,</p>
<p>possible reasons:</p>
<p>- the ACK is not routed through your proxy (missing record-route for the INVITE)<br>
</p>
<p>- 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)<br>
</p>
<p>Have a look to your SIP e.g. with "ngrep -qt -d any -W byline port 5060" on your proxy.</p>

<p>Hello Zhan,</p>
<p>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.<br>
