I have a mitel 3300 and recently purchased a UC360 conference room phone. I have the phone programmed as a generic sip device and have 4 multicall lines setup with the prime number. The phone connects and is able to make a call, however I am having trouble making a conference call. If I place caller 1 on hold, and press the second line, I dial the second number, it disconnects call one. If the second call is picked up, I have an option to add to conference. I select add to conference and dial call 1 again, it transfers my call to caller one. now caller 1 and call 2 are on the same call and the 360 is not involved in the call.
Any feedback would be much appreciated
thanks
