Since having VOIP Yealink put in the call quality has been bad, distant, quiet, muffled, and no upper frequency.
Our broadband is 80/20 with virtually zero use during calls, router setup on install.
The phone system works fine, but call quality isnt good.
Only once have I had a customer phone who showed the HD symbol on the phone and quality was perfect...
What are others doing for this? The other 100 other customers have never shown this symbol.
