Within the past few weeks, there have been threads on unofficial Vonage member forums that claimed Comcast had begun to block Vonage VoIP services. Representatives from both Vonage and Comcast have recently come forward to say that Comcast has not been blocking Vonage services.
Although representatives from Vonage said they had not noticed any problems with Comcast, Comcast and Vonage worked together to investigate if there was any issues with Vonage calls that were transmitted over Comcast's high speed Internet. Comcast said that Vonage indicated that the problem that had intiated the complaint had been an isolated issue and had nothing to do with Comcast high speed Internet service.
