Matt,

That's possible.  I've been struggling with this for a while.  

I recently transitioned from cable modem service to Verizon FIOS.  I didn't get a big change in behavior ( I was hoping so ).

My VOIP provider is Teliax.  My ping responses to the Teliax server are around 13/15 mS.

Can you recommend a method to test jitter or packetization?

  And/or periods of large jitter on your network connection.

    Could it possibly be a packetization rate issue with your provider?

      Many times the "speed" of an inbound voice call changes.  It's similiar

        A "speed" change is the best way to describe it, seems like the voice
      packets are being played out too fast.

      Can anyone explain what might cause this?  It doesn't always happen, and 
      seem unpredictable.

      Thanks,

      Jim
