If I start an IPVideoTalk meeting via Basic Plan, do I need to host the meeting with a GVC320x? Can I start or host the IPVideoTalk meeting without GVC320x?
Yes, users could host and start the meeting via the URL in the host's invitation Email or host the meeting by Host Code.
If my GVC is not the host GVC, can I add other GVC participants using their IPVideoTalk number?
If the GVC3200/GVC3202/GVC3210 is not the host in the meeting, this GVC3200/GVC3202/GVC3210 cannot add other GVC3200/GVC3202/GVC3210 devices into this meeting room. Only the GVC hosting the meeting can add other participants to the meeting.
My GVC doesn't have IPVideoTalk plan associated with it. Can I use this GVC for IPVideoTalk meeting?
For GVC with IPVideoTalk plan, it can be a meeting host. For GVC without IPVideoTalk plan, it can only be a meeting participant.
On my GVC3200/GVC3202/GVC3210, can I remove other participants from the meeting?
Yes. Users can remove any participants from GVC3200/GVC3202/GVC3210 “Conf Control” menu.

What happens after purchasing or renewing the plan?
When the plan of a GVC device is successfully purchased/renewed, the GVC device or owner can immediately use the IPVideoTalk conferencing services in the plan without obtaining the plan number from a zip file. Grandstream will be notified through email if the verification is passed or failed. If there is a problem with the order, the verification will fail, and the plan purchase/renew operation will fail either.
What is the recommended version of WebRTC browsers that clients can use, 32-bits or 64-bits?
It is recommended to use the same version as the computer's OS. Otherwise, users may encounter video/audio issue during the meeting.
What is the required bandwidth to attend a meeting?
Please refer to below chart for the required minimum bandwidth to ensure proper function of audio, video and screen sharing during an IPVideoTalk Web Meeting.
|
| Basic | Pro | Business |
| Audio | 90Kbps | 90Kbps | 90Kbps |
| Video | 1500Kbps (1.5Mbps) | 1500Kbps (1.5Mbps) | 2000Kbps (2Mbps) |
| Screen Sharing | 450Kbps | 450Kbps | 450Kbps |
What is the “Host Email” for the scheduled meeting?
The meeting host will receive a notification email which indicates “You have a meeting to host”. The Email will list meeting time, meeting ID, and Host code.
What is “Host code”? How can I find the “Host code” for a meeting?
The host code is a 4-digit number for WebRTC participants to join the meeting as a host. To find the host code for a meeting, please login to the IPVideoTalk Portal, go to the “Meetings” tab and select the specific scheduled meeting, the host code will be listed there. When joining the meeting via WebRTC, the participant can enter the host code to become the host for this meeting.
“Host code” can also be found in the notification Email “You have a meeting to host” to the meeting host Email address.
When I join the meeting from WebRTC using Safari as the browser, the web page always asks me to install plug-in. This happens even after I downloaded and installed the plugin. How can I join the meeting using Safari successfully?
When using Safari on MAC OS as WebRTC client, after installing the plug-in, please make sure to restart the browser manually by clicking on Safari icon on “Dashboard” and selecting “Quit” in the pop-up menu. Then you can open Safari again and use the meeting link to join the meeting.
When I use "Split Screen" option on my browser during IPVideoTalk meeting and other participant is sharing screen, I cannot see the content being shared and the sharing screen is black. How can I fix this?
This is caused by hardware decoding issue with H.264 on Chrome and Edge browsers. To resolve the issue, the user can open Chrome/Edge browser and enter "chrome://flags/#disable-accelerated-video-decode" or "edge://flags/#disable-accelerated-video-decode", and set "Hardware-accelerated video decode" as "Disable".
When the plan has already expired, is there a grace period before renewal?
There is no grace period. When the plan is about to expire in 15 days, there will be an email notification to ask the user to renew the plan. Once the plan expires, the user cannot use the IPVideoTalk conferencing service until the user renews the plan.
When the presenter is sharing the screen, I cannot see presenter’s PowerPoint pages being updated from my web browser. Why?
The presenter needs to make the PowerPoint full screen on the local PC before sharing the screen. Once the PowerPoint is in full screen then start sharing the screen, the participant should see the PPT page updating.
When trying to share presentation using WebRTC, after installing the add-ons and clicking on "Share", content sharing will not start, and the browser shows the prompt asking me to install add-ons again. What should I do?
Please make sure you are not using "Privacy" or "Incognito" browsing mode when installing the add-ons on your browser.
When trying to use my IPVideoTalk account on GVC, I received the message “Call failed”, how do I fix this?
When received Call Failed message, please confirm the following:
1. Ensure that your plan is active and has not expired. If your plan is expired the call will fail. This can be confirmed by logging in to the IPVideoTalk Portal in IPVideoTalk.com and review the Plans tab.
2. Confirm that the GVC you are calling has an active account.
3. Be sure that your GVC firmware is up to date, and the GVC you are calling is also up to date.
When using Windows 7 and Firefox, I get about 1% video packets loss, how is this resolved?
This is a compatibility issue with Firefox. You may click on icon "EnhanceWindowBuffer.reg" to download and run the registry file on your PC. After downloading it, restart your PC.
Where can I find the “Device Code” on the GVC3200/GVC3202/GVC3210?
“Device Code” can be found on GVC3200/GVC3202/GVC3210 LCD menu. To find the device code, go to the menu from the GVC -> Applications-> IPVideoTalk ->Settings. If the GVC3200/GVC3202/GVC3210 is booted up for the first time (or after factory reset), the “Device Code” is also displayed in Setup Wizard.
