Have not set up an account on the unit - thought I would try a video call via IP
Entered the address, far side started ringing.
Answered the call
Incoming/outgoing video on GXV3380 was fine
Image on far side - Tandberg EX90 - was garbled, but still getting audio.
Repeated this a few times, still the same
Tested with a Yealink video phone and it worked fine
I can test with other devices if you wish:
- Cisco CTS1500
- Poly Group Series 500
- Poly Group Series 7500
