We are currently in the process of migration our entire data centre into another organisation due to a recent acquisition.
I want to move a DHCP scope currently hosted on our domain onto another domain.
The DHCP scope is used to supply network details to our NEC VoIP phones.
The external party created the DHCP scope as request. We successfully assign the correct network details to the phones (IP, DNS and Domain details), the phones MAC address successfully added into the address leases field of the DHCP scope created. Excellent!!!
The only issue we found was that new DHCP scope option 161 is set to a string value, while on our DCHP scope the value is an IP Address. Since the value is a string the IP address required is now being converted to hex and then to IP which results in the IP address 49.48.46.56 been added to the DRS field on the NEC Phones. (See attachment for scope option comparison)
The question i have is... is there a way we can change the 161 scope option from a string to IP?
Sorry, i havent had the chance to test this. I will do later this week and will let you know how i go.
Thanks again for your help!

sorry for the late responce.
I found out that i could not change the 161 option at the new site. This was because it is currently being utilise for something else. i did test this with option 162 and changed it to "IP address" and worked ok. Great... I later found out that the 162 option currently bein ultilise for some wise devices as well...
So best solution will be to move the dhcp scope and update the DHCP helper on the switch as the only two option availalbe to be used for the DRS on the NEC VoIP phones is 161 & 162 and these are currently being used for something else!
I am pretty sure that the 161 and 162 have to do with FTP options.
161 is the server and 162 is the directory.
