We've recently upgraded our phone system to a CS1000 and are starting tests with the 1120E handsets which are going well.
Now I'm hitting a problem with the DHCP configuration for the phones. I've created a new scope in our main dhcp server for the IP phones which has all the information required to configure them and if I deactiviate my computer scope the phones pick up this information and work straight out of the box. However if both the data and voip scopes are operating the phones pick up addresses from the data scope and throw a DHCP parse error.
Can anyone point me in the right direction to get these 2 scopes working together?
I believe the Nortel phones initially start up on the data VLAN. Then via DHCP option 150 they pickup the voice VLAN info, drop the data VLAN IP and request an IP address from the voice VLAN.
