T58 - Firmware 55.9.0.9 VideoCall + MOH

[batsch]

Hi,

we bought a Yealink - Phone with Camera, i've updateted the Firmeware to the one mentioned in the subject line.

We are using Microsoft's Skype for Business Online "Plan". This is working pretty fine, we can make external Calls with VoIP and "normal" Skype-Calls.

It's not possible to make a VideoCall, which upsets me a bit. Although the Camera gets recognized on boot.
And i'm having trouble to deploy the MOH feature aswell. If uploaded diffrent Files via webconsole on the Phone, but if i put a call on Hold, all i heare is silence.

Is there anything, im doing wrong?

Kind regards
