might vary depending on firmware version, but from the 5.5.0 administrator guide:
call.defaultTransferType
permitted values:
Consultative or Blind
DEFAULT Generic SIP = Consultative, Lync = Blind
details: Set the transfer type the phone uses when transferring a call. If Blind, pressing the Transfer soft key immediately transfers the call to another party. If Consultative, pressing the Transfer soft key puts the call on hold while placing a new call to the other party. The user can press and hold the Transfer soft key to change the transfer type temporarily. The user can also set the default transfer type by going to Settings > Basic > Preferences > Default Transfer Type.
sounds like you need to set call.defaultTransferType="Blind" in your config file and test it.
I dont know if you can permanently remove consultative, but the admin guide is Very clear about how to set it to default to Blind Transfer.
