HI there,
I have to install an Innovaphone PBX system and the ipPhones are getting some of the basic-config via DHCP Options.
At the beginning I had troubles to find a config solution.
So here it is:
Innova Devices are requesting an additional DHCP Option “Option 43 Vendor-Specific Information”
In this option all additional Vendor- specific options are packed as a hex string.
Little Explanation:
“DHCP Option 43” with following Value: 0xcc03646575fa00
0x=beginning of hex-String
cc=204 Vendor- Option language
03= 3 following bytes (in ascii)
64=d
65=e
75=u
fa00=END
“DHCP Option 43” with following Value: 0xce02000afa00
0x=beginning of hex-String
ce=206 Vendor Option Voice- VLAN
02=2 following bytes (in dec)
00:0a=010 VLAN
fa00=END
Both together’ll look like this:
cc03646575ce02000afa00
Easyest way to put this Option43- String together:
Configuring the PBX’s own DHCP-Server with all the values and wireshark-sniffing the traffic while connecting an IP- Phone.
Than just copy and paste the Value of DHCP-Option43 and add an “0x” to the beginning of the string so that mikrotik DHCP- Server recognizes that this is an HEX- String.

Have fun with this.
