FAQ

General (4)

UCCCloud’s client can be started using any browser (Internet Explorer, Firefox, Chrome, Safari and Opera). Some browsers will need to be configured to permit JavaScript to run.
This could require the installation or update of the browser’s Java plugin. Currently, Firefox is the easiest to use as it runs JavaScript as a standard configurations.
Other browsers may require users to turn on JavaScript capability within the configuration controls of the browsers.
Echo in video conferences is frustrating for all parties involved. For users who use video conferencing often they have the proper equipment and their computer’s audio settings are optimized. The infrequent user is often frustrated or can bring down an entire meeting.
What causes echo?
There are a number of reasons why echo occurs in phone calls and video conferences. The largest culprit is audio that comes out of a computer’s speakers and picked back up by a microphone. This creates a loop that feeds an echo back into the meeting.
What is UCCCloud doing about echo in meetings?
We have built in Automatic Echo Cancellation (AEC) into the UCCCloud client. We have worked to optimize the current code and provided the ability for users to test audio settings before entering a meeting. We are also working on leverage some of the new AEC and noise cancellation code implemented as part of the WebRTC code. It is also good practise to use a proper speakerphone and/or headset to perform echo cancellation.
What can participants do about echo?
There are several remedies for echo.
1. Use a headset. With headsets there is no way for the microphone to pickup sound from the speakers.
2. Adjust your microphone input level and your speaker output level to at most 80%. By having the microphone lower this allows our echo cancellation code a buffer to work with. This is done in different places on different operating systems.
3. If you are utilizing an external microphone and/or speakers consider increasing the distance between the two and lowering the volume of the speakers.
4. Some computers (mostly laptops) have echo cancellation built in but this could be compromised by a high load on the computer’s CPU. Closing a few applications can help reduce load and allow this feature to operate properly.
5. If you are going to have video conferences frequently, consider a web cam that has a good quality microphone as part of the camera.
6. For larger areas (like a conference room) consider a quality echo cancelling microphone from a company like Revolabs. They have options for desktops to conference room.
UCCCloud’s online store offers a number of speakerphones that is able to tackle most meeting room environments.
Yes you can. In the invitation email, there is a “H.323 / SIP address:” provided.  All you need to do is to dial from your H.323 / SIP room system using the address given.
No. Just click on the link that you were sent and you can join a meeting. No user registration is required and your attendance can be totally anonymous.

Hardware (2)

UCCCloud supports Apple’s iOS devices version 4.3 or later on either an iPad 2 or iPhone 4S or later.
For Android devices (phones or tablets), UCCCloud requires operating system version 2.3.2 or later and API level 9 or later with at least a dual-core microprocessor.
UCCCloud will run better on mobile devices connected via Wi-Fi than on most carrier networks.
Earphones are recommended for use on mobile devices.
To join a video meeting, your computer or mobile device should fulfill certain minimum hardware requirements, especially if you intend to send and receive quality video and audio. At a minimum your computer should have the following:
An Intel Core™ Duo CPU or better or AMD equivalent
Microsoft Windows 7 (32 bit and 64 bit) and later
Mac OS X (10.7 and later)
Linux distribution (not older than 2 years if possible)
A web cam and speakerphone.

Network / Firewall (4)

Alternately you may see an error message saying, “The UCCCloud application is unable to connect to a server. See the technical FAQ on “Firewall and Network Address Translation (NAT) Support”. It is likely that you don’t have a port open on your firewall.
With some versions of MS Windows the system or antivirus program will ask you whether to authorize or block the Internet access for some programs depending on your security settings. Please make sure that you authorize all programs started by the UCCCloud application.
UCCCloud’s Hybrid Cloud works fine in a Network Address Translation (NAT) environment, the local or institute firewall (if any) should permit communication on UDP and TCP port 36015 both in and out. Your network administrator can open up these ports in your organization’s firewall.
A hard-wired Internet connection is preferred when connecting a PC other than a mobile device since UCCCloud streams each tile to the desktop.
Unlike other solutions, WiFi may work for a single person but the high packet loss over WiFi makes HD videoconferencing a substandard experience on many PC.
A reliable Internet connection with a minimum of 1-megabit per second download speed and a 256-kilobit per second upload speed is required.

UCCCloud Application (5)

To view the recorded video which you have downloaded or saved, you need to download the UCCCloud Player. You can download this from our Downloads section.
To activate the license after installation you must attend a live UCCCloud meeting.
Detailed documentation on the use of this player and its editing, conversion and export features can be found in the documentation.
Alternately you may see an error message saying, “The UCCCloud application is unable to connect to a server. See the technical FAQ on “Firewall and Network Address Translation (NAT) Support”. It is likely that you don’t have a port open on your firewall.
If this happens it will likely occur after you have typed in your display name or you have accept your previous display name. The exact error message will vary, but OpenGL will be referenced in the text. The video component of the viewme application requires the OpenGL 3D software engine version 1.5 or greater, which is supported by nearly all graphic chip sets sold in the past 4 years. If UCCCloud crashes or freezes attempting to join a meeting the probable cause is a graphic card that does not support OpenGL version 1.5 or greater.
To solve this problem, download and install the latest version of your graphical card’s driver from the manufacturer.
UCCCloud runs on Windows, Mac OS X, Linux, Android and iOS.
There are a few ways to join a UCCCloud meeting:
– Download and install the UCCCloud client software here
– Download and install the UCCloud Apple IOS or Android app from their stores
– Join via a web browser (Chrome or Firefox only) using WebRTC from here
