Wave Web users can change video resolution during video conference. When the user joins conference from Wave Web and shares video, by default the video resolution is 360p. To change video resolution, the user can click on the Options Gear icon on the upper right, open “Resolution” setting and select 1080p, 720p or 360p. Please note only one 1080p or 720p video feed is allowed in the video conference. If there is already a 1080p or 720p video feed in the conference, the user will not be allowed to change to 1080p or 720p.

For Wave mobile app, changing video resolution during conference is currently not supported.

When GVC3200 video conferencing devices are used with IPVideoTalk cloud service, up to 49 video feeds can be supported. However, when used with UCM6300 series, the max video feeds supported from UCM is 9. This is because UCM6300 series video conference is different from IPVideoTalk cloud service for mixing/forwarding the video feeds. The video feeds displayed on GVC3200 series also rely on GVC3200 series model's capability of SFU/MCU support.

- UCM6300 series uses SFU (Selective Forwarding Unit) to receive and forward video streams for each video participant. The video participant device receives multiple video streams from UCM for each video feed, and needs to support SFU to decode all video streams before displaying them.

- IPVideoTalk uses MCU (Multipoint Control Unit) which mixes all video feeds into one video stream so the participants only decode one video to see all parties' video.

For GVC3200/3202, it currently only supports MCU and can only display one video feed from the UCM which is the video conference moderator. Other participants' video feed currently cannot be seen. For GVC3210, SFU is supported and up to 9-way video can be displayed (conference control not fully supported on GVC3210 and compatiblity to be improved).

This will be supported in a future update.

- For conference with 4 or less video feeds:

The required bandwidth for each participant (in Mbps) = (A*1+B*0.172)*1.2+0.1

A is the number of 1080p video feeds (A = 0 or 1);

B is the number of participants excluding A. (B= Total number of participants - A);

1.2 represents the consideration of extra video bandwidth cost such as packet headers;

0.1 represents the bandwidth for audio.

- For conference with more than 4 video feeds:

The required bandwidth for each participant (in Mbps) = X*0.172*1.2+0.1

X is the number of total participants;

1.2 represents the consideration of extra video bandwidth cost such as packet headers.

0.1 represents the bandwidth for audio.

- For conference with screen sharing on:

The required bandwidth for each participant (in Mbps) = (X*0.172+0.512)*1.2+0.1

X is the number of total participants,

1.2 represents the consideration of extra video bandwidth cost such as packet headers.

0.1 represents the bandwidth for audio.

Note:

The above calculation applies to bandwidth required for each participant. To estimate the bandwidth required for UCM6300 series, please consider the number of participants and add them together.

For 1080p video: 1Mbps/15fps.

For 720p video: 512kbps/15fps.

For 360p video, 172kbps/15fps.

For screen sharing, 512kbps/5fps.

The above configurations can be modified per user’s preferences and it may impact the overall max number of allowed conference attendees depending on the trade-offs between video quality and max number of attendees.

- When joining a meeting on Wave Web or mobile app, select the Moderator role and enter the room’s host code.

- If you are already in a meeting and there is no moderator in the meeting yet, you can click on the upper right Options Gear icon and select “Moderate meeting”. Then enter the host code to become moderator.

During meeting, the existing moderator can transfer moderator privileges to another meeting participant.

Click on the Options gear icon on the top right of the page and select "Audio Settings". You will then be able to select the audio input and output devices you want to use for Wave Web.

The incoming call notification feature is added on UCM6300 series 1.0.3.x, Wave Android app 1.0.1.9 and Wave IOS app 1.1.9. There are currently a few limitations and will be improved in the future.

1. If the network condition is not ideal, the incoming call notification will be delayed up to 5 seconds. 

2. For iOS devices,  if the region is set to China, incoming call notification will not work unless the region is changed.

3. There exists known issue that the notification sent from UCM may be delayed or missed. This happens with probability and will be improved in future firmware.

Navigate to PBX Settings->General Settings and configure the "Conference Voice Quality" option. If set to “Full Band HD Voice”, 48KHz sampling rate will be used for Opus codec and the audio quality using Opus will be notably better.

Note:

When "Full Band HD Voice" is selected, "Max Number of Video Feeds" in the Call Features->Video Conference->Conference Settings page is currently limited to 4. Pending enhancements in future firmware releases may possibly lift this performance limit.

To set up your UCM6300 series system for the UCM RemoteConnect cloud service,

1. Go to https://gdms.cloud and log into your account.

2. Make sure that you have selected the Organization you want the UCM to be under.

3. Navigate to Device->PBX Device page and click on the Add Device button. If you have multiple UCM6300s to add to GDMS, you can also import an .xls/xlsx file with the appropriate format.

4. Enter the UCM6300’s MAC address, serial number, and its site.

5. The UCM6300 should appear online in the PBX Device page after a few seconds.

The UCM Remote Connect cloud service is in Open Beta Free Trial until July 2021. Thus, there is no need to pay for this service during this Free Trial period. Official subscription plans will be published after the Open Beta period ends in July 2021.

Only 1 moderator is allowed in the video conference. If there is already moderator in the conference, other participant cannot become moderator unless the moderator transfer the moderator to the participant.

- Please check your network stability. Unstable or slow networks can cause a delay in the appearance of video feeds.

- If needed, please contact UCM admin to check whether the UCM’s ICE and STUN/TURN server settings are configured properly.

Wave Desktop client is not available at the moment. It will be launched soon.
