So...was the desk phone working before the App extension was added, does it work if the App extension is removed or disabled? Are there other desk phone that work?

You said you created a test extension with no desk phone, then you say the desk phone is accessible though the IVR. Which desk set is this, as you said you did not create one in the test setup.

the fact that it is not reachable with a DID, may be another issue altogether.

All happened after the update to new version last week was working just fine before with app assigned... was hoping that the new version released this week would fix but it didn't...
It happens with app provisioned on extension and active remove and its just fine
