Sorry Bob, you'll have to be patient with me. I'm not absolutely sure how the scope has been set up.
In the Mitel 3300 administration, the DHCP server hasn't been enabled. So I assume this is handled by the domain controller?
All I know is that we have several Procurve switches been set up with several VLANs (one obviously for voice)
We also have around 25 other Mitel 5215 phones in the network, which are working fine, so I don't think there is a DHCP problem - it would appear that this is working ok, and the problem I'm experiencing is down to these particular phones instead?
Hope this helps.
Alex
