I'm trying to do a conference call on my Xperia U. But everytime I click "merge" button it displays this message: "Cannot make conference calls". I'm using a Telstra Locked Sony Xperia U and I phoned telstra about this and they claim it has something to do with the device. Can someone help me?
I dont think its a problem of ur device. Cause once my phone also show the same msg after pressing the Merge button. But Most of the time i can make a conference call without facing any problem. I think its kind a network problem of ur Carrier...
