AMI AtXfer in 1.4.42

Hi,

Is there any way to do announced transfers using the AMI in asterisk 1.4.42? I know that 1.6+ comes standard with the AtXfer AMI command but unfortunately upgrading our version is not an option right now. I’ve tried this patch: asternic.org/atxfer-manager.patch but it seems to be for older versions of 1.4.

Has anyone managed to get it to work? Any help will be appreciated.
