Route all calls to an extra bus. Lets say A. Send that bus back to callers as well.

The main location collects all calls on bus A and sends this bus A back. Then you have a mix minus and everyone can hear each other.

You can use Bus B for monitoring purposes if you set a different destination in the sound output settings. I believe that is the key for your problems. If all busses output on the same device the concept of a bus is infiltrated.

Hi There,

after quite a couple of calls I came to the result (or works for me best...)
Put every Call to a seperate audio bus.
i.g. Call1 D, Call 2 E (that´s meanwhile my way of routing the calls)

Put your headset for receiving the calls in the Background to Bus A

On B and C I collect callers to route them to the master.

This way you can:
have call 1 live presenting (call 1 to M)
& prepare call 2 (to A) via headset (to E)
& you won´t disturb any of your callers by another caller doing some bullshit like dropping
a headset

If you put all Callers to one Bus you will talk in caller 1s Presentation
while talking to caller 2.

If you send your Audio to a audio desk make sure you get n-1 back from your audio engineer!

If you then have 2 callers presenting together or put in a Q&A Session you must
connect them then concerning the Audio Feed (Call1 M&E, Call 2 M&D)
