IVR使用了JRTPLib库，某次异常观察输出日志，提示OnSSRCCollision
关于SSRC的介绍
Identifies the synchronization source. The value is chosen randomly, with the intent that no two synchronization sources within the same RTP session will have the same SSRC. Although the probability of multiple sources choosing the same identifier is low, all RTP implementations must be prepared to detect and resolve collisions. If a source changes its source transport address, it must also choose a new SSRC to avoid being interpreted as a looped source.
我的问题是， ssrc冲突具体含义是什么，会在什么样的情况下发生？发生之后有什么影响（比如单向通之类的）
