We have 4 OBI1062s which (once connected via Ethernet rather than WiFi) work pretty well. I'm having an issue with conference calls.
I can add a second call, by making an OUTGOING call, to a conference when the only active call is INCOMING. I press the CONFERENCE button, make the other call, and press CONFERENCE NOW. All good.
I cannot, however, add a second OUTGOING call if the other active call is also OUTGOING.
What am I doing wrong?
