BCM 450 GR5 DHCP not working

[nooop]

I have my scope setup, and DHCP is enabled for Phones Only, but my sets are grabbing DHCP from the network. I have many other sites that work just fine. I have all the latest patch's installed. I have 80 phones to install tomorrow and it would suck to have to do them all manually. Help please.

Thanks

Unfortunately the phones don't know that you set up a DHCP exclusively just for them and that the other one is for computers. They will grab an address from whichever one responds first. The only way to isolate them is to put the phones on a separate VLAN that doesn't have a DHCP server or a relay agent on it. Of course the BCM would also need to be on the voice VLAn. That would reduce congestion, jitter, and make the VoIP experience better.
