I have here a GDS3710 that works with a GXP2130 and 2170, but with GRP2614 no video, but audio works and door open as well.
Interesting, I will also try to test this.
We have the same issue. Audio and door open works, but no video. Video does work on our other gxp and gxv phones.
Thanks, we had file a bug request for this.
