候選：
linphone是一個成熟的跨平臺sip軟電話，但是它的android版本剛剛出來，但是目前還不支援視訊通話。底層使用的庫是eXosip。模擬器上開源執行，能夠撥打和接聽電話，但是沒有語音，只是狀態會成為connected。
sipdroid也是開源的，比較成熟，支援視訊通話。使用的是Mjsip庫。模擬器上提示：not suitable data network。
Imsdroid支援視訊通話，底層庫是doubango。模擬上提示：network not activi。
關於doubango庫，也不單單是sip的，如下：
doubango is the world's most advanced open source 3GPP IMS/RCS framework
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.
目前瞭解到的開源sip協議棧有：
C語言的：eXosip，doubango
java語言的：Mjsip，JAIN SIP
