             Summary: WebRTC Client No Audio after 60 seconds on Windows Only
                 Key: ASTERISK-24929
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-24929
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
    Affects Versions: 11.16.0
            Reporter: JoshE
            Severity: Critical


Seen a strange set of behaviors with Chrome WebRTC clients on Windows OS only.  ChromeOS and OS X are unaffected.

After exactly one minute, Asterisk throws a:

[2015-03-31 23:25:47] WARNING[30439][C-00000002]: res_srtp.c:407 ast_srtp_unprotect: SRTP unprotect failed with: authentication failure 110

This is generally preceded by a handful of authentication failure 10s, but the call continues to pass audio normally:

[2015-03-31 23:25:45] WARNING[30439][C-00000002]: res_srtp.c:407 ast_srtp_unprotect: SRTP unprotect failed with: authentication failure 10

At the 60 second mark, when the 110 error occurs, all audio is lost.  I've tried this with 1.4.2 version of libsrtp, as well as the latest github code.  All produce exactly the same behavior.

Anyone else experienced this?
