4-way conference on VVX450



I have a VVX450, firmware 5.9.1 (latest as of this post). I am looking to do a 4-way conference.

- I have feature.nWayConference.enabled="1"

- When I join the first two participants, I do have a "manage" button to mute participants (if I understand correctly, it means nWay is indeed enabled.


I just don't know how to add a third one. I do not get the "conf" option anymore at that point.  What's the exact key sequence to add a fourth participant?

This is all good for a 3-way conference, but I'm looking for a 4-way conference. This is explicitely set in the provisioning files as an enabled feature.


The exact sequence (including what is missing) is:


- Call someone

- Press more than conf

- call the second party

- Once second party answers, press more and conf

- ???


We have have a three-way conference.  How do I add an additionnal participant?

Thank you - dissapointing that Polycom removed such a feature from newer phones, but at least I'll stop finding a way to do something undoable.

N-way might be supported by your PBX (so N-way call is hosted on your PBX, not the phone), if it does - you'd need to enabled "network conferencing" by entering proper URL in the phone's config.


But yes, I agree that's a commonly asked question and I wish VVX phones were like 550s/650s in this way.
