With Koodo home phone on the ZTE VoLTE box, I’m supposed to be able to do conferencing. However, when I connect to a 2nd party I’m only able to toggle back and forth between them, not talk with both at once.
The method I’m using is (1) call the 1st party, (2) press [FLASH] to obtain dial tone and call the 2nd party, (3) press [FLASH] to reconnect with the 1st party.
What am I doing wrong (or not doing)?

Well, I finally found a manual online for this device (it’s a WF723CA). It says to complete the 3-way call after making contact with the 2nd party, press the  key, then [flash].
