HP5412 and Cisco Call Manager

Hi
I have 2 CME's running on seperate subnets and seperate vlans with 1 HP switch for PoE and vlanning.

For some reason only a portion of phones are working, which I think are on CME1.

HP 5412 - http://pastebin.com/m19411969
CME1 - http://pastebin.com/m7012bf4
CME2 - http://pastebin.com/m6a04a1fa

Some phones are picking up an IP from the DHCP server on vlan 1, these are the phones in vlan3 I think as vlan2 phones work fine, again, I think.

Any help would be greatly appreciated.

Kind Regards
Stefan

I can see the phone is connnected by running show cdp neighbors, even though it isn't going in to the correct vlan? and isn't talking to the CME?

CDP is a cisco propriety protocol, not tcp/ip-based.
default it will use vlan-1.

You have several uncertainties in your post ("I think"), so please check those items if you want us to help.

in your config's i find this :
vlan 2
untagged E2
vlan 3
untagged E3

I assume E2 and E3 are where the CME's are connected?
if so, then why this :
vlan 1
no untagged E2
It would be logical also for E3 or also not for E2.
here's also something strange :
vlan 3
untagged E3
tagged C9-C24,E1-E24,F1-F24,G1-G24,H1-H24,Trk1-Trk8
Is this from the real config, or an editted line?
E1-24 contains E3 and the port cannot be tagged+untagged in the same vlan, so I expect
tagged C9-C24,E1-E2,E4-E24,F1-F24,G1-G24,H1-H24,Trk1-Trk8.

then you speak about adresses from the dhcp-server on vlan-1, but they should come from the CME's own dhcp-server.
CME1:
ip dhcp pool IP_PHONES
network 192.168.1.0 255.255.255.0
option 150 ip 192.168.1.254
default-router 192.168.1.254
CME2:
ip dhcp pool NEW_BLD_IP_PHONES
network 192.168.2.0 255.255.255.0
option 150 ip 192.168.2.254
default-router 192.168.2.251
lease 7

please check what adresses the working phones and the non working phones have.
