After upgrade to 188.8.131.52 Sip video Call for incoming Calls will not work!
I use 2N Helios IP Video Kit (Door Phone with Grandstream GXV 3275 Phone and all works fine.
But after upgrade to Firmware 184.108.40.206 you will not see any video from incoming Calls. If you call the Door Phone you will see the Video.
I have checked all part but no success ( Reboot of all Devices + latest FW)
Now i have downgraded the S50 Firmware to 220.127.116.11 and all works fine again.
Please fix the issue.
