anything changes and if not look at going up to 5.5.x, thanks!

What version are you running?

My test with 5.5:

$sht(a=>+18884441111) = 1;

xlog("L_INFO","match right 111 $shtcn(a=>~%111)"); xlog("L_INFO","match left 111 \
$shtcn(a=>%~111)"); xlog("L_INFO","match left +1 $shtcn(a=>%~+1)"); \
xlog("L_INFO","match right 444111 $shtcn(a=>~%4441111)");


kamailio[12832]: INFO: match right 111 1
kamailio[12832]: INFO: match left 111 0
kamailio[12832]: INFO: match left +1 1
kamailio[12832]: INFO: match right 444111 1
