Can I use UCM6300 series as MCU for Grandstream GVC3200 series video conferencing device to support more than 9 video feeds (max for UCM6300) during UCM video conference?
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).
Can I view the existing chat history after joining a meeting from Wave Web?
No, pre-existing chat history will not be available when joining a meeting.
Does Wave iOS/Android mobile app support chat functionality?
This will be supported in a future update.
For video conference, will the number of video feeds and voice codec affect the number of attendees allowed in the conference?
Yes. Please see examples to illustrate the relationship below.
Note:
By default, UCM6300 series has “Full Band HD Voice” enabled which allows Opus 48KHz sampling rate to be used. If the users prefer more than 4 video feeds or more attendees in the conference, please log in UCM6300 series web UI as admin, navigate to PBX Settings->General Settings and configure the "Conference Voice Quality" option to “Broad Band HD Voice” instead.
Model | Video feeds/screen sharing | Voice codec | Max attendees |
UCM6301 | 4 video feeds + 1 screen sharing | Opus (48KHz sampling rate) | 12 |

For video conferencing on UCM6300 series, how can we calculate the bandwidth required for each participant?
- 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 video conferencing on UCM6300 series, is 1080p used for all the video feeds?
No, only one video feed can be 1080p or 720p. Also, if there are more than 4 video feeds during video conference, or if there is screen sharing, the video bitrate for the 1080p/720p video feed will be reduced.
For video conferencing on UCM6300 series, what’s the default video bitrate and frame rate?
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.
GDMS no longer detects the UCM6300 series as online after a period of time. How can I fix this?
Please check your firewall to make sure ports 3478 and 6514 are open. GDMS communicates to UCM6300 series through these ports.
How can I become the meeting moderator when using Wave Web or Wave mobile app?
- 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.

How can I obtain the login information for Wave Web?
- As UCM6300 series admin:
Log in UCM web UI, select extensions which has email configured and click on “More”->”Email Notification” to send account information to the configured email for the extensions. The email notification will include the UCM public URL, extension number and password for the users to log in Wave Web. (The UCM public URL address can also be viewed from UCM web UI->Value-added Features->UCM RemoteConnect->Plan. This is the URL for the admin to send to users.)
- As an end user:
Please contact your UCM admin to obtain the login URL, extension number and password. If you have received UCM account email notification, the email will include UCM public URL, extension number and password for you to log in.
If you have registered your UCM extension on GXV3350/3370/3380 on latest firmware and can log in the GXV3350/3370/3380 web UI, you can go to the phone’s web UI->Status->Account Status and click on “Enter” under “GS Wave” for the registered account. This will redirect you to the Wave Web URL for you to use on PC.
How can I use an external audio speaker or microphone instead of my computer’s built in options when joining the meeting via web browser?
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.
How can I use UCM6300 series behind NAT?
- If you are using UCM RemoteConnect service, the UCM6300 series behind NAT can already work with your Grandstream end devices, Wave Web and Wave mobile apps without additional NAT settings in your network routers. However, if the end user is experiencing audio issues, please navigate to UCM6300 series web UI->Value-Added Features->RemoteConnect->Plan Settings and ensure Media NAT Traversal Service is enabled. By default, this is already enabled.
- If you are not using UCM RemoteConnect service:
Method 1: Configure port forwarding for your UCM. This will be limited by the NAT type of the network that UCM and end devices are located.
Method 2: Use self-deployed or available STUN/TURN server. On UCM6300 series web UI, admin can navigate to PBX Settings->RTP Settings, manually enable ICE Support and configure STUN/TURN server settings properly.
How come the incoming call notification for my mobile Wave app doesn't work?
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.
How come the video or screen sharing is not clear during video conference?
If the participant is using Firefox web browser to share video or screen from GS Wave web and the participant’s PC currently has high CPU usage, Firefox will automatically reduce the resolution of the shared video or shared screen from this participant. Therefore, the other participants may see video resolution reduced or presentation become blurring during that period.
How do I configure the audio quality of conferences?
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.
How do I get the login QR code for my extension?
There are 2 ways:
1. Ask the UCM system administrator to send the SIP account information email to you.
2. If you have logged in Wave Web already, click on your extension number on the upper right corner and select "My QR Code" option to display your QR code. Then you can use your Wave mobile app to scan to QR code to log in.

How many moderators are allowed in the video conference?
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.
I can see duplicate participants on the “Participant List”. Why does this happen?
This is caused by abnormal disconnections from the related party. For situations like these, if there is no RTP detected from the participant within 90 seconds, they will automatically be removed from the meeting.
I cannot see people’s video feeds in a video meeting. Why does this happen?
- 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.
I cannot use my deskphone, Wave web and Wave mobile app with the same SIP extension at the same time. Why?
In order to use the same SIP extension on deskphone, Wave web and Wave mobile app at the same time, the SIP extension must have 3 or more concurrent registrations allowed. By default, the number of concurrent registrations is set to 3. To confirm or change this setting, please log in UCM6300 series web UI as admin, navigate to Extension/Trunk->Extensions, edit the extension option “Concurrent Registrations” to be 3 or more.
Note:
To register SIP extension on deskphone or log in with the extension on Wave web / Wave mobile app, the same SIP registration password is used (which is the “SIP/IAX Password” on UCM6300 series web UI extension settings).
Is there a Wave Desktop client for UCM6300 series?
Wave Desktop client is not available at the moment. It will be launched soon.
My SIP account QR code no longer works. After scanning it with the Wave mobile app, it does not fill in the SIP server information and account credentials. How can I fix this?
This could be due to either the UCM6300 series PBX firmware or the Wave mobile app not being updated to the latest version. Please make sure both the UCM6300 series PBX and Wave app are up-to-date.
