I am located in 416 area code (Canada) and have also noticed quite a variable call quality using Voipcheap to North American numbers. Calling European numbers (France, Ireland, UK) usually results in excellent call quality, whether through Voxalot via dial plan routing or directly through IP phone registered with Voipcheap.

I suspect the call quality is related to the PSTN provider's ability to provide gateway termination capability at the time of the call to the area code called. Maybe they switch to a lower BW codec to maximize the use of available BW at the time??

I have used PSTN termination through les.net when I have this problem, with the added advantage that the service allows you to set the outgoing Caller ID info. This is very handy when activating your new replacement credit via the bank's automated service !

Hope this helps. All the best
