Years ago Time Warner Cable exerted enough pressure on AOL that when the company was a part of Time Warner that the senior team forced AOL to kill their fledgling VOIP service and ultimately AIM phone line, a service which could have rivaled Skype in its era.
Well it seems that Time Warner Cable which now is deploying WiFi hotspots that are under the TWCC Passpoint SSID are still down on VOIP. Basically their firewall prohibits calls via Cisco's Jabber or CounterPath Bria from working with hosted or cloud VoIP service.
This experience mirrors what is experienced with their home cable modem/router/access point from Arris. Those devices default to blocking SIP traffic from any provider but Time Warner Cable. Of course at home the firewall can be turned off but when you're out and about the traffic just won't pass on their network.
Given the FCC is picking on hotels for blocking WiFi devices one has to wonder when they set their sights on the cable guys blocking third party voice services or any other traffic type.
