Re: [SR-Users] Any clever ways to strip down a user portion of an RURI?

I haven't tried, but an alternative idea that worth checking:

xavp_params_explode("$rU", "u");

$xavp(u=>npdi) = $null;

xavp_params_implode("u", "$rU");

$xavp(u) = $null;

Cheers, Daniel

I have a similar need and have not found any shortcuts. Nevertheless, I hope the following snippet might help generalise the problem:

    $var(new_ru) = ‘';

    $var(i) = 0;
    while($var(i) < $(rU{param.count,;})) {
        $var(k) = $(rU{param.name,$var(i),;});

        switch($var(k)) {
            # Strip off 'npdi', keep all else.

            case 'npdi':
                break;

            default:
                if($(var(new_ru){s.len}) > 0)
                    $var(new_ru) = $var(new_ru) + ';';

                $var(new_ru) = $var(new_ru) + $(rU{param.name,$var(i),;});

                if(!strempty($(rU{param.valueat,$var(i),;})))
                    $var(new_ru) = $var(new_ru) + '=' + $(rU{param.valueat,$var(i),;});
        }

        $var(i) = $var(i) + 1;
    }

    $rU = $var(new_ru);

For a test RURI value of:

sip:14045551212;npdi;moo;rn=14045550000@sip.evaristesys.com

This yields:

sip:14045551212;moo;rn=14045550000@sip.evaristesys.com

More parameters to strip out can just be added to the ’switch’ statement.

Have a need to strip out various parameters from the user portion of the RURI and/or the To (npdi, etc). Does anyone have any clever methods for doing so that don’t involve just brute forcing through the individual parameters?
