VoIP (SIP) Call

• Immediate interaction with the studios.
• Connection simplicity on networks over which you have no control (public Internet, Wi-Fi from various locations).

• Configured at a low bitrate, it ensures continuity even with restricted Internet.
• Configured at maximum quality, the audio is equivalent to direct sound in the studios.

When the studio operator calls the MX2200:

• The MX2200 display shows a dialog box to Accept/Reject the call.
• A ring in CUE is played.

To be able to receive incoming calls on the MX2200, it is necessary to disable call encryption in the communications software used.In Linphone: Preferences → Calls and Chat → Encryption = None.
If encryption is active, the console will not be able to take the call.

• The MX2200 sends the Program (PGM) signal to the Studio.
• The Studio returns a mix-minus: the studio floor signal without the console’s own signal.
• The console mixes the program signal plus the studio return in CUE.
• The user can remove the PGM signal from the headphones to listen only to the Studio return (see the Monitoring section).
