DHCP server Second Subnet Vendor Based IP Allocation

Hi Experts
  We have a situation in which we are rolling out IP phones and the ip Phones require IP address in a different network as to the domain
the details are as follows

Domain network: 192.168.50.0/24
IP Phones Network: 10.10.10.0/24

We need to create a scenario where the dhcp allocates the addresses to the IP phones in the 10.10.10.0 network
I was informed about the vendor class option in the DHCP options
The Vendor Mac Identifier is 00:15:65
Also if this requires configuring the option in ASCII or Binary how we do that....

Also we need to give a gateway of 10.10.10.200 to the phones which i assume is just gateway option for that subnet but the main problem is to make the phones get ip in the 10.10.10.0network

Also is it possible that the two networks can talk to each other if required in the future.

But we are having trouble implementing it
Could you please help us with the steps i need to follow as the setup is driving me nuts

*******Thanks to the experts in advance*******

If I'm not mistaken, you can assign an IP to the MAC Address of the IP Phone.

But to automate the process I m sure there is a way u can just configure the vendor identifier to automate the allocation to the devices from that vendor...

The reson why we are trying the class if or vendor ID is becuse of the VOIP provider claming that they do it all the time, And not that we have asked them to do it for us, They are not able to do it....

So kind of they lied to us that they do it using vendor id and now they do seem to have a clue about it...

Please suggest what would be the appropriate setup for now....
As previously stated, you REALLY should isolate VoIP traffic. Itnsolves your immediate problem, but also solves pain points you'll have in the future if you dont (dropped calls, sound quality, severe lag, etc).

If you don't have the drops and absolutely cannot run them (which, take my word for it, you eventually will do anyways to alleviate network related issues once deployment is live), just save time and statically set IP and gateway. That gateway issue will have you touching each device anyways, so setting an IP in addition is suddenly less of a big deal.

Thanks for your support Guys
The provider apologized for providing misleading information and accepted that proper hardware, Vlan's and QOS is the right way to go ahead with the setup
Thanks Experts
