RCConnection错误：setSDP错误：无法设置远程提供sip：使用SDP调用而不使用DTLS指纹

Question

I am using Restcomm's Android SDK and trying to configure it to our servers, but getting the following error:

RCConnection Error: setSDP Error: Failed to set remote offer sip: Called with SDP without DTLS fingerprint

But when I changing back to Restcomm servers it works fine.

I have tried to search it at Google and Git, but the solutions offered there did not help. Any idea how to solve the issue ( please explain in details since I am new in WebRTC ) ?

EDIT:

In case when I call from mobile to web or from the web to web it works fine. The problem occurs only when the mobile tries to accept the call.

请确保您的服务器支持Media和ICE Lite程序的DTLS-SRTP。
