Yeah Rusty-

Sorry about that.  Probably a bit inelegant in phrasing.  There is a larger bug here that we worked around, but it more appropriately belongs in another ticket.  We'll get that submitted separately.

In the meantime, for anyone experiencing that flow, an upgrade to Chrome 42, in beta as of today, will resolve this failure to decrypt audio.  It's quite likely a libsrtp 1.5 upgrade is required.

I would recommend closing this ticket out.

>      Security Level: None
>    Affects Versions: 11.16.0

> 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?
