H.264 V20

[Jlidds]

Is there anyway to allow H.264 video codec in V20 or any plans to bring it back?
We used to have video intercoms call a ring group, and the video showed up on Fanvil X6U handsets. This works on systems that were upgraded from V18 to V20; however, any clean/new installs of V20, do not allow video.

Since the existing sets are still working, could it be a setting in the new template, that has a function set incorrectly. .
This post deals with Grandstream , rather than Fanvil, but, perhaps there is something similar going on.

Hello,


Sorry for posting this in the wrong section — I don’t yet have the privileges to post in the proper category.


I am facing an issue with video on the 3CX Android App.


Setup:

• 3CX Cloud with an SBC in my office
• Grandstream devices: GXV3275 video phone, GDS3710 doorbell/intercom
• Clients: 3CX Web App and 3CX Android App

Configuration:

• All Grandstream devices are set to use H.264 for video
• The GXV3275 works perfectly with both audio and video on the Web App, the 3CX Android App, and the GDS3710
• The GDS3710 works fine with the GXV3275...

I have a V20 with H.264 based door phones, calling a H.264 capable desk phone, and they work fine in direct calls and ring group calls.

Maybe you have a queue, not a ring group. Queues answer the call themselves before polling the agents, so video is not established there from the get go.

Also keep in mind that X6U supports video from doorphones, but X6U-V2 does not.
