Voice2go error 11503

I'm trying to make an international call using Xfinity voice. Is this the right way to call?


dial 011+country code+phone number


I try on my home phone. Sometimes, it is dead silence. Sometimes, it connects to people speaking languages that I don't understand. So, no idea which country it connects to.


I also try on my iphone using the Xfinity Connect app. It returns this error:

Unable to connect your call at this time. Please try again later. (11503)


Anyone has any idea what is wrong?  Thanks.
