Hi, I have a call like following: Which B have to make. 1. Reference: ========== A0 = first caller B = Operator C = Support Engineer A1, A2, A3 is invited in the conference call for that session, which is made by B, only B gets out when all of them are talking 2. Draw it: ======== A0->B->C | / +----------/ +A1 +A2 +A3 3. Result: ======= A0 + A1 + A2 + A3 getting Support by C as a conference call. B made this connections and gets out when all are connected. Is that possible using FreeSwitch? Thank you Best regards
