It does not work in Microsoft Internet Explorer, Edge, Opera or Safari.
Note: Interpreters making use of ZipDX multilingual capabilities must use Chrome.
(2) Internet Access
To deliver clear, uninterrupted sound to and from a conference the web phone requires a reliable, continuous internet connection. It needs only a 100 kbps in each direction, making it usable on even slower DSL services.
Wi-Fi connections tend to be variable, which can lead to dropped calls or gaps in conversation. Therefore, we recommend conference participants using the web phone use a wired Ethernet connection to their local network switch or router.
(3) Audio Devices
The web phone requires access to a microphone and speakers.
These may take one of several forms:
- The built-in microphone & speakers on a laptop
- An analog headset connected to the computer’s internal sound card
- A USB-connected headset (pictured above left)
- A USB-connected speakerphone device (pictured above right)
- A Bluetooth wireless headset or speakerphone device (pictured above middle)
While any of these will work, we’ve found that a headset with a boom-mounted microphone consistently delivers the best experience for a single participant.
