System requirements for telephone broadcasts

For events with Telephone as the live acquisition source. This article details the system requirements for broadcasting a Live event or recording a Simulated Live event over the phone or with VoIP audio.

To join the Live Studio and moderate or present, your system must meet the following minimum system and hardware requirements. At least 48 hours before the event, run the system test with the hardware and network you will use on the day of the event.

If you're unable to open the Live Studio, access might be blocked by a firewall or your company network security rules. Review our network requirements and make sure the ports and IP ranges in the Webcast Presenters - Audio Events column are permitted. If you're unsure of your settings, contact your IT Administrator.

For the best audio and video quality, we recommend that presenters use a:

When you join the Live Studio and connect with VoIP audio, you must grant it access to your mic to connect your audio.
