iPhone 上的 VoIP over 3G,SDK 发生了什么变化?
我一直在研究 SDK3.2,以了解在 3G 网络上直接通过 IP 进行呼叫的新功能,但我在 API 差异中没有看到任何明显的内容。这只是苹果在低级私有框架上允许的事情还是也反映在公共框架上?如果是的话,哪个框架、类、方法?
谢谢你的帮助
I've been looking at the SDK3.2 to find out about the new capacity to direct call over IP on 3G network, but I don't see anything obvious in the API diffs. Is this just something Apple allows on a low level private framework or does it reflect on the public frameworks as well? if so, which framework, class, method?
thanks for you help

我认为一切都没有改变。这主要是手机运营商可能施加的许可限制。
I don't think anything has changed. Its mainly a licensing restriction likely imposed by cell phone carriers.
我不认为这是 Apple 在 API 级别强制执行的。将加密的 VoIP 数据流与其他类型的加密数据区分开来并不容易,您可以很容易地绕过这种限制。他们要求 VoIP 应用程序自行强制执行,以通过 App Store 审核。他们根本不会再对应用程序强制执行此限制。事实上,一些应用程序无需更新操作系统即可在 3G 上运行。
I don't think this is something Apple enforced at the API level. It's not easy to distinguish an encrypted VoIP data stream from other kinds of encrypted data and you could circumvent such a restriction very easily. They required the VoIP applications to enforce it themselves to get past the App Store review. They simply won't enforce this restriction on apps anymore. Actually, some apps already work on 3G without an OS update.
