Reports about VOIP traffic being blocked by network operators are becoming more common in wake of customers complaining their telephony service is being degraded. In the United Arab Emirates, Internet users are complaining they have been unable to access Skype.com to buy SkypeOut minutes. The culprit seems to be Etisalat, the UAE's only ISP. In the U.S., there have been reports that Vonage's service is being blocked at times by phone companies. In Canada, the major broadband operators have promised the CRTC they will not engage in this kind of nefarious activity.
