Alexander Traud updated ASTERISK-16898:
---------------------------------------

    Attachment: srtpROC-LE_for_libsrtp2.0.x.patch
                srtpROC-LE_for_libsrtp1.6.x.patch
                srtpROC-LE_for_libsrtp2.1.x.patch

This issue was about Nokia Mobile Phones and especially those using the operating system Symbian/S60. The fault was within that implementation, not in libSRTP, not in Asterisk. The last phone model based on that operating system was released five years ago in June 2012. Therefore, I am closing this issue by updating the patch for libSRTP versions 1.6, 2.0, and 2.1.

Furthermore, I changed the warning message in Asterisk to signal whether audio/voice (RTP) or statistical (RTCP) messages are affected. That change splits-off the issue of Nokia Series 40 based phones which faced the same warning message when it came to RTCP. The last phone model based on that operating system was released four years ago in September 2013.

If you still face that issue with other VoIP/SIP phones, please, create a new issue report and mention the phone (brand, model, and its firmware version).
