hi - I built a PHTM (500) that is set to call fwd (FTR DCFW) to another phone....but when I call the PHTM DID from my cell phone - once it fwds the call to the other phone it is not passing the callerID of my cell but passing a generic number for our company. is there a way to pass the callerID of the cell phone thru the PHTM?
