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?

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;
Cheers,
Daniel

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