Cold transfer in Genesys PSDK

Can anyone share cold transfer/conference code block in Genesys PSDK? I have searched online but I am unable to find it.

If you are a developer, all what you needs is view Genesyslab.Platform.Voice.Protocols.Dll where are all request what you need - RequestSingleStepTransfer and RequestSingleStepConference, etc.

Thanks for help.
