Hi all, After much stuffing around I've worked out how you can continue to make ad-hoc audio conferences using the 3CX Softphone in 15.5 SP2. NOTE: To 'manage' callers you will require the Web Client, but you can add participants without it. How To: Creating the Conference Start by making a phone call to the first participant of the party, once established, click on 'Conference' You will now be transferred to the Conference Room with your private conference. Adding Participants To add another participant, click on 'Line 2' and dial the next participants number. Then once in communication with them, click the 'Conference' button again. 3CX will then transfer them and you into the Private Conference you first created. You will then have three participants in your ad-hoc conference. You can continue to do this until you run out of Concurrent Call license or your SIP/Voice Channels. Managing Participants To Manage the participants in the conference like you could in SP1 and before you now need to login to the WebClient. The fastest way to get to Conferences in the WebClient is to go via the Softphone Conference button and then click on 'View Conferences'. NOTE: You WILL require your WebClient password to login if you are not already logged in. Then click on 'My Private Conference' and you can see the participants in the conference and easily disconnect them (Or re-connect them if they drop). Note: The only way to truly 'End' the Conference is via the WebClient, or hope all participants hang up. Hopefully this helps some people with the fun we're all having with these undocumented changes.
