I’m generally please with my Deco XE75/AXE5400.  I get great download speeds and so-so upload speeds which I attribute not to my Deco unit, but rather my ISP.  In any case, my one gripe is Deco’s support of my iphone 12 voice calls. 

When I place voice calls through my Deco WiFi, the sounds quality is significantly worse than basic LTE service from my cellular provider.  The issue isn’t bandwidth.  Both the Deco and the iphone have the latest software.

Has anyone else having a Deco voice call problem?
