@JBean3329. Thank you so much for responding. For as long as I have been a tech and in this IT field, I have always hated vendors that keep things proprietary and not allow the end-customers to do what they want with their own equipment. I had reached out to ICON Networks and pretty much received the finger and they did not allow me to even access any documentations to figure it out on my own. I knew it was possible and even randomly guessing encapsulation option codes, I was able to relay the CCU IP address. My phone support person finally gave me a document that outlined the DHCP options and sub-options. I now have it working and below is my solution for anyone else having this issue. I can't wait to get a different phone system and move away from ICON and their partners.
IPs are for demonstration.
-We have tagged VLAN ID 200 for voice network (192.168.200.0/24) on our switches
-We default untagged traffic for data vlan id 100 on (192.168.100.0/24) on our switches
In Window's DHCP console, I created scopes for both subnets. Under scope options on VLAN 100 (Data) - which is what every device will connect to first, option 43. In option 43, the following header bytes, vendor id, and sub-options are needed:
01 08 49 57 41 54 53 55 49 50 02 04 c0 a8 c8 02 04 02 00 c8 (type it in w/o spaces)
01 = required header
08 = 8 bytes to follow
57 41 54 53 55 49 50 = IWATSUIP (this is configurable on the phones, but by default this is the specific vendor ID IWATSU uses)
02 = (sub-option 2) - Data header for point to CCU IP
04 = 4 bytes to follow
c0 a8 c8 02 = this is the IP address to the CCU card, use a decimal to hex converter. For my demostration, this is translated to 192.168.200.2
04 = VLAN ID sub-option, Data header for assigning VLAN to the phone
02 = 2 bytes to follow
00 c8 = VLAN TAG 200 - use hex to convert.
There's additional sub-options you can still add, such as QOS and VLAN priority levels.
05 02 03 xx, xx will go from 00-07 :: VLAN Priority
06 04 00 xx 01 yy, xx is for voice payload, yy = voice signaling dscp :: QOS
I hope that helps anyone else needing this in the future.
