为什么 Android 2.3 中包含的本机 SIP 堆栈无法在 3g 上工作?
我想知道为什么 Android 框架(自 2.3 起)中包含的本机 SIP 堆栈不能在 3g 上工作?
这是否与谷歌对其合作伙伴可能有的任何法律或限制有关?
此外,有人知道是否有计划取消该限制吗?
谢谢
I was wondering why does the native SIP stack included in the Android framework(since 2.3) does not work over 3g?
Could it have something to do with any laws or restrictions google may have with his partners?
And furthermore, does anybody know if there is any plans to remove that restriction ?
Thx

在 GingerBread 中,SipManager 设置为工作仅在无线网络上。
但从 4.0 开始,此配置已已更改为
false
因此,理想情况下,本机 sip 堆栈应该适用于从 Ice Cream Sandwich 开始的 3G。
但同样,如果手机是由服务提供商出售的,那么该功能可能已被禁用。因此,出售的解锁手机可能完好无损。
要检查是否支持 Sip over 3G,您可以使用 api
In GingerBread, SipManager is set to work only on wifi.
But from 4.0 onwards, this config has been changed to
false
So Ideally native sip stack should work on 3G from Ice Cream Sandwich onwards.
But again if the phone is sold by a service provider, then this might have been disabled. So phones sold unlocked may have this intact.
To check whether Sip over 3G is supported you can use the api
