Is anybody successfully doing attended transfers on Yealink T29G's or T46's? I've been trying the methods at: https://www.3cx.com/blog/voip-howto/blind-attended-transfer-yealink/ and https://www.3cx.com/blog/voip-howto/blind-attended-transfer-yealink-t48-t46/ with no success. These methods lose the initial caller or at best result in a blind transfer. I wish we could do attended transfer using the BLF fields on a T46, but we've had no luck with that either. Any help will be greatly appreciated.
