Solved No Video - Grandstream GDS3710 & Yealink T58

[Francois92]

Hi 3CX support and community members,

Hope you are all doing well and having a nice day!

I am experiencing a strange problem with our GDS3710 door phone and Yealink T58 desk phones and would really appreciate any help or input regarding the issue.
We are able to make successful video calls from the GDS3710 to an extension provisioned on the 3CX webclient but not to the Yealink T58 or 3CX Softphones.

I have tried changing the resolution the camera streams at but haven't had any luck.

GDS3710 Config:

• 3CX Version, 16.0.8.9
• Is the 3CX Server Hosted and where? - Hosted in a VPS environment.
• IP Phone Make/Model/Firmware - Grandstream GDS3710 (v1.0.7.23) + Yealink T58 (v58.85.0.5)
• Provisioning Method: SBC
• Has the Firewall Checker passed: YES
• Are custom Phone Templates being used: NO

The only 3CX Client that supports H264 is the 3CX Webclient so the scenario you describe is not expected to work on the 3CX Apps.

Regarding the call between the two IP Phones, do bear in mind that in a video call, the media traffic just passes through 3CX so there is no transcoding taking place. That said, if both devices are set to use the same codec and all parameters of that codec match, it theoretically should work.

Hi Chris, thanks for getting back to me regarding this matter.
Do you perhaps have any other parameters I could check except for the video codec? My H.264 payload type is set to 99 by default, is that fine?

I'm afraid I wouldn't be able to help you with specific settings, however, there is a thread regarding the same exact devices which may just contain all the information you need: https://www.3cx.com/community/threads/grandstream-gds3710-help.77074/page-2#post-352175

Thanks for the link, I have gone through the configuration steps in that thread but have unfortunately not had any luck with the video streaming to the Yealink T58.

Try changing the door phone, video setting, profile to "Baseline" from "Main Profile".

Hi Jonathan, thank you sir! Changing it to "Baseline" resolved the video streaming problem.



Your assistance is greatly appreciated!
