Hello All,

I installed a new ShoreTel system and I discovered that the ShoreTel servers do not hand out DHCP. The vendor we are working with gave info on setting up option 156 in the Windows DHCP scope. Right now, we are replacing the Cisco system and they were on a 10.10.1.x subnet and scope for the phones. Our switches and routers are all Cisco devices and have VLAN999 assigned for the phones and VLAN1 for data traffic.

We are running out of IP addresses for the internal DHCP scope so I will need to change that at some point; however, wondering if anyone can help me out? I have a dedicated DHCP server and while I did have two servers (one with about 70 percent of the addresses and then the second as a failover), I went to one because with the phone system, I don't want to make it very hard to manage, etc...

Read so much about option 156 and Cisco switches but somehow, it just isn't working. It would be nice to have the Cisco router hand out the IP's but when we had that setup, the phones get an internal IP address of 192.168.1.x, see the Option 156 and then when they are supposed to then get the 10.10.1.x address, they don't. They stay at the "Getting DHCP" screen. I then setup a Windows DHCP server with a second network card that had the IP of 10.10.1.9 on it and then the DHCP range was 10.10.1.50-200. The phones did the same thing! AHHHH!!!!

Killing me. thoughts?
