Blind Transfers on Yealink 38g return completed calls with "Transfer Failed"

I have provided pcap and configs to Yealink in a repeatable scenario.

The answer they gave back to me was to set this in my config file.

transfer.hang_up_after_success_trans = 3

This does resolve my problem. There not a setting for this in the GUI. So unless you are using auto provisioning, you have no way to set this.

Tested with Yealink T42G and T46G.
