Thank you so much! I removed any $fU/$rU manipulation in favor of 
uac_replace_from/to and so far, results have been much more consistent. 
Appreciate all the help!

Hello,



Yes – as said, you should use the uac functions to change the From/To headers. 
This is recommended over using the $fU or $tU.



Cheers,



Henning

Hello,



My apologies, I seem to have ​posted an incomplete code segment. I only seem to 
have issues when it comes to replacing $fU (before using uac_replace_from) - 
the same action on $rU seems to work properly. In the below situation, the $fU 
variable should be updated with the plus, but the $avp(uacreplacefromdisplay) 
variable has the value of the original $fU, not the updated one. Is this 
practice redundant, and should actions on $fU and $rU be avoided in favor of 
uac_replace_to/uac_replace_from?





            $fU = "+" + $avp(src=>countrycode) + $fU;

            $avp(uacreplacefromdisplay) = $fU;

            $avp(uacreplacefromuri) = $fu;



        if ($avp(uacreplacefromdisplay) && $avp(uacreplacefromuri)) {

                
uac_replace_from("$avp(uacreplacefromdisplay)","$avp(uacreplacefromuri)");

                $avp(uacreplacefromdisplay[*])=$null;

                $avp(uacreplacefromuri[*])=$null;

        }



            xlog("$ci - converting domestic caller id number to $fU ($fu) - 
$avp(uacreplacefromdisplay) $avp(uacreplacefromuri)");




Thank you so much for your help!

Hello,



If you want to change the From (or To) header content, you should use the “uac” 
modules replace_from/_to functions. They will transparently make sure that both 
end-points get the correct header content.



Cheers,



Henning

Hi all,

I'm running into some issues with E164 conversions and was wondering if there 
was a decent standardized method for conversions. Conversions using $rU seem to 
be working great, but $fU is behaving badly. This is what I have so far:

    xlog("$ci - caller id was $avp(src=>callerid)");



    if($avp(src=>callerid) =~ "^\+"){

            xlog("$ci - caller id already E164");

    }else if($(rU{s.substr,0,$(avp(src=>countrycode){s.len})}) == 
$avp(src=>countrycode)){

            $avp(src=>callerid) = "+" + $avp(src=>callerid);

            $fU = $avp(src=>callerid);

            $avp(uacreplacefromdisplay) = $fU;

            $avp(uacreplacefromuri) = $fu;

            xlog("$ci - Adding plus to make caller id e164");

    }else{

            $fU = "+" + $avp(src=>countrycode) + $fU;

            $avp(uacreplacefromdisplay) = $fU;

            $avp(uacreplacefromuri) = $fu;

            xlog("$ci - converting domestic caller id number to $fU ($fu) - 
$avp(uacreplacefromdisplay) $avp(uacreplacefromuri)");

    }



Previously, I'd found a suggestion mentioning using uac_replace_from in the 
route[RELAY] (which is the purpose of the uacreplacefrom avps), but $fU does 
not appear to be changing its value. Is there something I'm doing incorrectly?
