Dell 6248P switches with ShoreTel IP 480 phones
After attempting to configure a separate scope/VLAN for our ShoreTel phones, I am still unable to get the phones to pick up an address from the correct scope - with the settings I have listed below it is still picking up from the data scope. When I look under Admin options>Ethernet it doesn't even seem to be picking up the VLAN ID if that helps to provide any insight. I have read very similar threads but nothing identical to the issue we are having so I thought I'd post if someone is able to take a look. I have the 156 option set in DHCP for the VoIP scope according the the ShoreTel for the manual (tried setting it on data scope in addition to VoIP scope - still no luck), have tested with different configurations in the switch and verified with the ISP that the router has the correct IP helper addresses pointed to the correct VLAN on the router (I can provide the router config, as well if necessary) and also have it set up in the switch for VLAN 30 (not sure if that is redundant), as well but still at a loss so I'm starting back at the beginning. Phones will be acting as switch. In the OpenManage Switch Administrator, I have Voice VLAN>Configuration set to VLAN ID = 30. I will post the config in case anyone has a chance to look and sees something obvious that would prevent the phones working when the configuration is set. Working on module 1, port 14 (set in bold face to make it easier to find, and I have also tried on 2/g45 to give an idea of some of the settings I've tested with), I probably could have posted a lot more information, just sure what was relevant so any questions please ask and I'll be glad to answer to the best of my knowledge:

Discovered that when I remove the 156 option from the Data scope the phone boots up fine but still grabs an IP address from the Data scope instead of the VoIP scope. Seems like it may be a VLAN issue given that information, I'll keep updating if I find anything else.

I suggest removing the vlan association command, as it can sometimes get in the way of things.
On the interface itself can you try a config like the one below? I think some of these lines are default, but still worth putting them in.
interface ethernet 1/g
spanning-tree portfast
switchport mode general
switchport general pvid 1
switchport general allowed vlan add 1
switchport general allowed vlan add 30 tagged
lldp transmit-mgmt
lldp notification
lldp med
lldp med confignotification
lldp med transmit-tlv inventory
voice vlan 30
voice vlan auth disable
exit
The show lddp and show lddp interface commands can help get a look at the lldp status.
let us know if any of this helps.

Thank you so much for the response! I gave that a try but still timing out when trying to obtain an IP address via DHCP. The show lldp commands are showing the link is up, transmit is enabled, receive is enabled and notify is enabled. I did find out that when I have option 156 enabled in the data scope the phone times out, but if I remove option 156 from the data scope (leaving it enabled in the VoIP scope) the phone will boot up, just won't grab an IP address from the VoIP scope so I looked around in our ISPs portal and found the config for our router and noticed they have the ip helper-address set globally and not for VLAN 30 (not sure if that would even make a difference) and also it looks like they might have put an incorrect IP address for VLAN 30, as well - still waiting for someone to confirm but I will update as soon as I hear back. Thank you for the quick response! I'll update when I hear something back.

Those setting may play a role, will be interesting to hear if it helps.
LLDP-MED works in conjunction with the voice VLAN to identify the device/traffic on the interface and place it on the voice VLAN. If the switch and phone are not communicating properly through LLDP, then
Some other areas to think about:
- Some phones require specific TLVs to be in place. The switch has some default TLVs, but sometimes additional ones need to be configured.
- I have seen issues with some phones if they are on older firmware. Updating the phone and switch to the latest firmware can sometimes help.
- In some extreme conditions where it seemed like no amount of changes would place the phone on the voice vlan, some people have manually configured the phones to send tagged traffic for the voice VLAN. This can be an easy set it and forget it config, as long as you dont have many phones.
