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?

If you have received this e-mail in error, please immediately return it to the sender and delete it from your system.
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.

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;

Confirmed it works! Brilliant; definitely much better than my solution. Thank you for that.
Will it work with $xavus too?
