first, I would like to share with you that the MAC showing on Yealink phone(Menu - Status - General - MAC) is permanent, Every phone with a Unique MAC address. So it is not relate with the method the phone obtained the IP address.

It's confusing to someone setting up the phones but ok.

Not sure what you are trying to say here.

Yes the phone gets an ip address using the wifi dongle.

I don't need to change the mac. I need the phone to request the proper configuration file based on the mac address like any other phone does.

It's DHCP.

It's set up like any other dhcp server. But again the phone gets an ip address that is not the problem.

This is all correct. The problem is that when the phone system presumably arps the ip address, arp returns the mac address of the current used interface which now is the wifi interface. To explain this lets say the mac address of the built in ethernet adapter is 11111111 and lets say the mac address of the wifi adapter is 22222222. Arp returns 22222222 so a config file is created by the phone system that is called 22222222.cfg. Good so far. Now the phone boots. When it boots it looks at the tftp server and should be looking for a file called 22222222.cfg because that is the active interface. But's it's not. Instead it is looking for 11111111.cfg which is not created because it's not the active interface. Can you see the problem?
