Has anyone gotten this to work? I have the 3CX Phone registered using the provision file, and a T46 provisoned automatically as well. The 3CX Phone does connect and come up with CTI below the display. When you call the extension everything shows properly on 3CX phone, but no commands work. I can't answer an incoming call or dial out from it. I did a PCAP from within the Yealink interface and I see the commands coming from 3CX to dial, answer, etc., so I don't believe it is a 3CX problem, but more of an issue with the Yealink. I don't have the PCAP handy at the moment but will post back with it shortly. I read in the very short post about this that the first time you "pair" them you should get a prompt on the display of the Yealink to allow access. I have not gotten this on 3 installs now on any phone I have tried it with. Is there something else in the Yealink that needs to be configured? I know about the push XML settings, but I don't think they apply. Could it have to do with the new feature in 12 that changes the default login on the Yealink?
