UberConference is made to work with most users' browser type and internet speed, plus no downloads are required. We do have some requirements, however, to get the best experience. Those include:
- 100kbps connection speed (both upload and download speeds)
- Latest Chrome browser for screen sharing (no canary or developer versions)
Worried that your computer still won't connect? Make sure to check the following areas:
Test Call Quality
Launch a call quality test to review these areas:
- Microphone
- Audio Playback
- Network Connectivity
- Data Transfer
- VoIP
- Audio Input
If something's wrong, we'll let you know and give you the steps to fix it.
Screen Sharing
Make sure that you've set up the following for screen share:
- Latest version of Chrome browser (no canary or developer versions)
If you're only viewing a screen share, you can use the following browsers:
- Google Chrome
- Mozilla Firefox
- Internet Explorer
- Safari
- Opera
- Microsoft Edge
Mic & Speakers
If your computer doesn't have a built-in mic and speakers, we recommend using a headset (like Plantronics USB). Plus, headsets cut down on background noise and any chance of echo.
Video Streaming
Recommended bandwidth for HD video (720p)
For 1:1 calls, the recommended bandwidth is a minimum of 1.2-1.5 mbps up / down.
For group calls, 1.2-1.5 mbps and 3 mbps down.
Routers and Ports
You'll want to make sure your router/gateway has the SIP ALG disabled and that you've opened the following ports on your firewall:
| Protocol | Ports | Direction |
| TCP | 80/443 | Out |
| TCP | 6800/5222/5223/7060 | Out |
| UDP | 5060/5061/7060/11000/16600 to 16998/19305 | Out |
| UDP | stun.l.google.com/19302 | UDP outbound |
| "" | "" | UDP bidirectional |
| UDP | 16384 to 32768 | Out |
You can also restrict outbound traffic to the following domains:
dialpad.com
dialpadcdn.com
highfive.com
ubervoip.net
stun.i.google.com
What are these ports used for?
80/443: WebSockets to communicate with our servers
6800/5222/5223/7060: Outbound calls
5060/5061/7060/11000/16600 to 16998/19305: Outbound calls
stun.l.google.com/19302: ICE protocol to determine public address
16384 to 32768: Only open these if your network doesn't use D-NAT
Usually, there's no need to turn on QoS on your router unless you have a large network with several thousand employees.
Awesome
