One more tid-bit. I believe that somehow my carrier may be getting passed the incoming caller's caller ID. For test I changed my Pub OLI to blank and a few of the other extensions and called out. They all worked.

I then changed my Pub OLI to several of the number in my DID range of xxxxxxx600 to xxxxxxx799 and those all worked as well. But when I change it to something outside my range I got my call rejected right away and a busy tone.

Is there a setting on the BCM400 that will enable passing the incoming caller ID out that I should disable?
