Unfortunately, I wasn't able to locate your account. You can send me an email with the mac address & I'll lookup your account. When you say you are not able to do 3 way calling most of the time, does this mean you are successful at times?
Yes, if you have premiere, 3 way calling is included.
Just to recap:
3 way calling has to be done in front of the Ooma device.
Once you establish a call on line 1, pressing line 2 will provide you another open line to dial out & placing line 1 on hold.
Once the call on line 2 is established, you are pressing both line 1 & 2 together until both light up. Is this correct?
