Dear community, I hope someone can help me here as Grandstream does not, even though I have an open ticket since september 11th.
My problem: I have a GDS3710 and a GXV3275 (high end ;D ;D haha) phone. When I setup the GDS3710 to call the phone with direct SIP extension or direct IP the phone rings and shows an auto preview of the Video (that remains black most of the times) EVEN THOUGH THIS IS DISABLED in the settings! >:( >:( >:( >:( >:( >:( >:( >:( >:(
This happens with the latest stable and BETA firmware.
Again, I reported this to grandstream in september and they promise me every time to test it but no solution.
Does anyone have these devices to test?
