Alexander Traud updated ASTERISK-24911:
---------------------------------------

    Attachment: fingerprint.patch

Even today, some DTLS-SRTP implementations face that issue. Therefore, I attached the mentioned change as file (for use in scripts). Hopefully that helps you as administrator to debug (at least) this issue more easily. If the case is the cause, do not forget to report to the author of your DTLS-SRTP implementation to handle "sha" case-insensitive.

> In DTLS Connect mode Firefox(37/38) is not responding for Client Hello. The same setup is working fine for Firefox Stable (<= 36) & Chrome Canary (<=43). No Error logs are observed in Asterisk. No Error Responses from Firefox. Tested with Asterisk 11 and 13. Firefox 37 (current beta channel) is going to release by 03-31-2015, as per the release calendar. So all the Asterisk WebRTC Gateways will going to effected by next couple of days with Firefox Update.
> Note: When i tested with SIPml5 in Firefox-37 with (webrtc2sip+doubango) it is working fine, so issue is with Asterisk only
