[SR-Users] Guidelines on E164 conversions

[Henning Westerholt]

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

Subject: [SR-Users] Guidelines on E164 conversions

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?
