Unable to call some 1-800 numbers

Is anyone having issues calling 1-800 numbers? It's been fine for me for almost a year up until last month, but now I get a message "You can not call this # from your area code 1-3-60 (???). Below is response from my provider: .... that sometimes our customers have problems calling Canadian 800 numbers from Canada because they are routed through the U.S. and therefore look like they are coming from the U.S. rather than from Canada. I did send a trouble ticket to my advisor concerning this issue. The response was that we have been actively seeking a resolution for this for some time now, though we do not have one as of yet. Because the majority of the issue lies with Canadian telecom companies and how they receive the information, an accurate time frame of when this will be resolved cannot be forecasted.
