我知道告诉iPhone呼叫某人的唯一方法是调用"tel:0123456" URL，Apple SDK中记录了该URL的URL方案.

The only way I know of telling the iPhone to call someone is calling a "tel:0123456" url, the URL scheme for that is documented in the Apple SDK.

如果可能的话，没有记载，但是我认为不是.

If it is possible it is not documented, but I think not that it's possible.
