Oracle Session Boarder Controller - HMR

Hi,

looking for some help. I have this HMR setup to remove 719 (from the To and RURI if the number starts with those 3 digits) from calls. Im trying to make it so that I can add any other combination of 713, 711, 724, etc... but not sure how to setup the HMR (see below)
