Which Free DID has better call quality for you?

[testing123]

GC + Gizmo OR GC + IPKALL + FWD ??

I have both setup and I hear a bit of scratchiness on the GC + Gizmo.
But Gizmo rings practically INSTANTLY when someone dials the GC# -- it is hands down the first to ring.

Just curious what the voice quality is like for you between the two.
