android上的电话

候选：

linphone是一个成熟的跨平台sip软电话，但是它的android版本刚刚出来，但是目前还不支持视频通话。底层使用的库是eXosip。模拟器上开源运行，能够拨打和接听电话，但是没有语音，只是状态会成为connected。

 

sipdroid也是开源的，比较成熟，支持视频通话。使用的是Mjsip库。模拟器上提示：not suitable data network。

 

Imsdroid支持视频通话，底层库是doubango。模拟上提示：network not activi。

 

关于doubango库，也不单单是sip的，如下：

doubango is the world's most advanced open source 3GPP IMS/RCS framework for both embedded and desktop systems.
The framework is written in ANSI-C to ease portability and has been carefully designed to efficiently work on embedded systems with limited memory and low computing power and to be extremely portable.

 

目前了解到的开源sip协议栈有：

C语言的：eXosip，doubango

java语言的：Mjsip，JAIN SIP

 

补充：
