Callerid problem Asterisk n Polycom

I have Polycom 320’s connected to an Asterisk server, which is connected to an Audiocodes box at a remote location that has a PRI connected to it.

My question: Is there anyway to just send the callerid number to the phones without the names, or maybe strip the name if it is a certain name??

My Problem: The screen is small and when someone calls from a cell phone the callerid name is “Wireless Caller”, and you can not tell what number it is coming from.
