RE: Attended tranfer communigate problem
Do you press the OK button to attended transfer?
If you press the transfer button, the transfer is blind transfer.
If you press the OK button, the transfer is attended transfer.

If you have the correct steps and the attended transfer still can't work.
Please tell me what screen show when the attended fail?

And please help us to get the PCAP and syslog and config.bin files. We can check something from them.
You can get more info from the link: http://forum.yealink.com/forum/showthread.php?tid=1319 

Last, for the old firmware, the T29 only have V80 version, would you please tell me what firmware do you want?
And how many phones do you have and how many phones have this issue?
