<tt>Hi Anton,<br>
<br>
by default, the module does auto restore of the FROM/TO hdr. The
restoring is done in the traffic flowing in the opposite direction
than the initial request. So, the uac_restore_xx() is NOT an
uac_undo_xx() !<br>
<br>
As I understand, you do serial forking and for you want to do
different, or not to do, uac_replaces for each branch. If this is
the case, you need to do the uac_replace_xx() in the branch_route
- by doing this, the change will impact only that branch, without
any effect on the other branches.<br>
<br>
<br>
branch_route[change_from]<br>
{<br>
if (</tt><tt><tt><tt>$avp(furi)!=NULL)<br>
</tt></tt> uac_replace_from("</tt><tt><tt>$avp(furi)</tt>");<br>
}<br>
<br>
route {<br>
$avp(furi) = "...";<br>
t_on_branch("change_from");<br>
</tt><tt>t_on_failure("missed_call");<br>
}<br>
<br>
</tt><br>
<tt>failure_route[missed_call]<br>
{<br>
$ru = "..";<br>
</tt><br>
<tt><tt> $avp(furi) = "...";</tt> # if you want a different FROM
URI<br>
</tt><tt><tt><tt>$avp(furi) = NULL; # if you want to keep the
original URI<br>
<br>
....<br>
</tt></tt>}<br>
<br>
Regards,<br>

Help me to understand. In request_route i make replace from and
to fields.
<div>After an unsuccessful attempt to invite, I try to direct
the call to another place and again I need to replace the from
and to fields. But instead of replacing, new values are simply
added<br>
</div>
<div><br>
</div>
<div>route {</div>
<div> ...</div>
<div> route(rewrite_header);</div>

</div>
<div> setflag(need_uac_restore);</div>
<div> ...</div>
<div> route(rewrite_header);</div>
<div>}</div>
<div>route[rewrite_header] {<br>
</div>
<div> if (isflagset(need_uac_restore)) {<br>
xlog("L_INFO", "[ $ci ] - restore from and to
fields\n");<br>
uac_restore_from();<br>
uac_restore_to();<br>
}<br>
</div>
<div>
uac_replace_from("",<a>"sip:$avp(fromuser)@$avp(fromdomain)"</a>);</div>
<div> uac_replace_to("",<a>"sip:$avp(touser)@$avp(todomain)"</a>);</div>
<div>}</div>
<div><br>
</div>
<div>in the end I get such fields<br>

<div>it simply appends the new value to the old and does not
replace it<br>
</div>
<div>changing replace modes in uac module does not change
behavior<br>
