Hello,
assigning to $fn, $fu or $fU is offered as a convenience way to update
parts of From header, but the changes are not applied immediately, like
the other operations done over the SIP headers -- see more details in
the FAQ:

https://www.kamailio.org/wiki/tutorials/faq/main#why_changes_made_to_header…
In your case, try to do those changes only in branch_route.
Cheers,
Daniel

Hi,
Just to add one more point that $fU & $fn I'm checking not in script
but in SIP packet. So using sngrep i see in SIP packet from header
where $fU and $fn are "1234567+123456".

Hi!
I have small problem. When I assign $fU or $fn in request-route
and then one more time I make new assignment in
branch_route. Instead of rewriting it is just concatenate needed
value at the end. lets assume $avp(cli)=1234567 and
$avp(cliplus)=+1234567. So if in request_route I
do $fU=$avp(cli); and then in branch_route $fU=$avp(cliplus);. $fU
becomes one string: "1234567+1234567". Is it a bug or I missing
something?
Here is config snippet:
request_route {
...
route(MY);
...
}
route[MY] {
...
$avp(cli) = "1234567"
$avp(cliplus) = "+"+$avp(cli);
$fU=$avp(cli); # here $fU=1234567
$fn=$avp(cli); # here $fn=1234567
route(LCR_ROUTE);
exit;
}
route[LCR_ROUTE]
{
if(!is_method("INVITE"))
return;
if (!load_gws("1",$rU,$avp(cli))) {
send_reply("503", "Error loading gateways");
exit;
}
$var(i)=0;
while($(avp(lcr_gw_uri)[$var(i)])!= $null){
xlog("L_INFO", "loaded
gw_uri_avp[$var(i)]=$(avp(lcr_gw_uri)[$var(i)]) \n");
$var(i) = $var(i)+1;
}
if (!next_gw()) {
send_reply("503", "No available gateways");
exit;
}
xlog("L_INFO", "request-uri $ru \n");
xlog("L_INFO", "$avp(lcr_gw_uri), $avp(lcr_id)\n");
xlog("L_INFO", "flag $avp(lcr_flag) \n");
t_set_fr(0, 4000);
t_on_failure("RTF_LCR_ROUTE");
t_on_branch("BRANCH_CUST");
route(RELAY);
exit;
}
branch_route[BRANCH_CUST] {
if ( $avp(lcr_flag) == 4) {
$fU=$avp(cliplus); #here $fU=1234567+1234567
$fn=$avp(cliplus); #here $fn=1234567+1234567
}
}
