Current Android SIP API does not support creating conferences. 当前的Android SIP API不支持创建会议。 However the functionality could be implemented on a SIP Application Server (AS). 但是，该功能可以在SIP应用服务器（AS）上实现。 In theory, it would be possible to use FACs (Feature Access Codes) at server side. 从理论上讲，可以在服务器端使用FAC（功能访问代码）。

Example: You are in a call with +1234567890 and want to add +1234567890 to the call. 示例：您正在使用+1234567890通话，并且希望将+1234567890添加到该通话中。 by using makeAudioCall API with a supported FAC in the peerProfileUri , lets say "tel:*111#+1234567890#+1234567890#" a capable AS could place the second call create a conference. 通过在makeAudioCall API与受支持的FAC一起使用，可以说“ tel：* 111＃+ 1234567890＃+ 1234567890＃”，有能力的AS可以peerProfileUri第二个呼叫来创建会议。

Also are there any limitations of using that library like can it work on 3G or 4G? 使用该库是否也有任何限制，例如它可以在3G或4G上使用？

There are no limitations, it can work on 3G/4G as long as bandwidth for audio is enough. 没有限制，只要音频带宽足够，它就可以在3G / 4G上运行。 Audio mixing is normally done at server side, so each participant would send/receive audio as in a regular call (no additional streams). 音频混合通常在服务器端完成，因此每个参与者都将像常规呼叫一样发送/接收音频（没有其他流）。
