Registration problems with Cisco IP Phone 6921

[AYTOIAM2009]

Hello.

We have two types of Cisco IP Phone connected to our Catalyst 4503:

Cisco 8961 and Cisco 6921.

With Cisco 8961 we have no problems at all.

Nevertheless, some of the Cisco 6921 IP Phones, when are connected to the switch, get the IP address from the data vlan DHCP server, instead of getting it from the voice Vlan DHCP server. If I connect a Cisco 8961 IP Phone in that port, everything is ok.

Does anyone know anything about this problem?

Thanks.
