thanks for the reply. we bought it locally and it's just my first time to install it in our company. it gives me a lot of trouble before i manage to install it successfully. I ask for help in some of my friends and they told me that I need to install CTM to get this feature in bcm 400. I guess I just have to buy and install this one for my system to get it working.

I got confused on what to do in element manager for this feature. there is a box for caller ID feature but I can't put a check on the box. but anyway, I will try first to install CTM device and see what will happen.

thanks again......

Always expect the unexpected!!
