Hi
Please i have a colleague who is having this issue. I need your assistance to get it resolved.
Teams Blind Transfer to a Call Queue fails when you select the "Ringback if there's no answer" option. If you click the Transfer button to transfer the call to a Call Queue and select the "Ringback if there's no answer" option, Teams immediately calls back with the message that the call transfer failed.
If you do not select the "Ringback if there's no answer" option, the transfer to the Call Queue works. The "Ring back if there's no answer" option works when you transfer to a user.
It looks like, when the "Ring back if there's no answer" option is selected, Teams does not even send a SIP REFER to transfer the call.
Is this a known issue?
