Yet Another Chinese Telco To Block VoIP
from the no-more-cheap-calls dept
Over the past few months, there have been a few stories about Chinese efforts to block various VoIP systems. Usually, the focus is on Skype, but phone-replacement VoIP systems like Vonage are clearly an issue as well, as anything that routes around the traditional phone system is a problem. Luckily for the Chinese, some US firms are more than willing to supply filtering technology. We already noted that one such firm, Verso, was supplying its Skype-filter to an unnamed Chinese telco. Now, another firm, Narus, claims to have sold VoIP blocking technology to Shanghai Telecom Co. In this case, the company claims its only for phone-replacement VoIP. Even though the company does offer a Skype-filter, the telco has not purchased it in this case (yet). So how much longer until the various VoIP providers start figuring out ways to encrypt and hide their traffic so that it’s indistinguishable from other forms of traffic?
