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_headers...
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 } } Jurijs
