Apple has been notoriously rebuffing VOIP applications from its app store but no explanation was available. But now it seems it wasn’t Apple which was refusing VOIP applications instead AT&T did not allow VOIP traffic through its network. Finally AT&T is saying that it will allow VOIP traffic through its 3G network, means go ahead for Skype and Google voice and many more VoIP applications.
This is because FCC has scrutinized how Apple and AT&T handle VoIP apps for the iPhone , specifically, Apple’s continued rejection of Google’s Google Voice app. In short FCC is pushing for "net neutrality," which prevents carriers from blocking Internet communications, even on wireless networks and AT&T had to yield to mounting pressure.
At the moment this might sound a good news, but the load of new VOIP traffic might strain even less stable AT&T network which is causing many dropped calls and less stable VOIP calls, but our fingers are crossed and we are hopeful that now Google Voice and Skype will prevail on iPhone and users will be able to expand their communication horizons.
