Hi, I receive INVITE like this:
INVITE sip:client_xxx2004@domain.org SIP/2.0
and I get from an $avp(CLIENT) the value "client_xxx".
I need to strip from $rU the lenght of $avp(CLIENT), this is:
# Original $rU => client_xxx2004
strip($avp(CLIENT));
# New $rU => 2004
Unfortunatelly "strip()" doesn't accept a PV as parameter, but a static
integer.
Any suggestion on how to achieve my goal?
Thanks a lot.

Great, s.substr does allow pv as parameters:
$(var(x){s.substr,$var(num),0})

does len() accept a pv argument? if it does, you can then uses s.substr
transformation.

Yes, I already implemented it by using that:
$var(client_regex) = "^" + $avp(AVP_CLIENT) + "[0-9]+";
if $rU =~ $var(client_regex) {
$rU = $(rU{s.substr,$(avp(AVP_CLIENT){s.len}),0});
xlog("L_DBG", "--- Replacing rU: $oU -> $rU \n");
}
Thanks.
