Hi,
I have several Yealink phones that I updated from *.81.0.60 to *.81.0.61.
With the updated firmware no audio could be heard in calls between extensions.
I have the 3CX Professional Edition Version 15.5.5, cloud hosted in Google Cloud Platform on Debian.
Here I summarized the combinations i tried
If .60 T27P calls a .60 T27P -> Audio OK
If .60 T27P calls a .61 T27P -> No audio
If .61 T27P calls a .60 T27P -> Audio OK
If .61 T27P calls a .61 T27P -> No audio
If .60 T27P calls a .61 T46G -> Audio OK
If .61 T27P calls a .60 T46G -> Audio OK
If .61 T27P calls a .61 T46G -> Audio OK
If .60 T46G calls a .61 T27P -> No audio
If .60 T46G calls a .60 T46G -> Audio OK
If .60 T46G calls a .61 T46G -> Audio OK
If .61 T46G calls a .61 T27P -> No audio
If .61 T46G calls a .60 T46G -> Audio OK
It seems there's something special with .61 T27P receiving calls...
Is there anything I can do to fix this?
