Kinsey Moore updated ASTERISK-21323:
------------------------------------

    Attachment: whitenoise_fix.diff

Attached diff that fixes the bug for my reproduction.  The change still needs to be verified to be correct (it looks OK according to the SRTP, RTP, STUN, and TURN RFCs I've looked at so far).

> Hi all,
>  
> we have just updated our Asterisk 11 testbed from 11.2.1 to 11.3.0-rc1. Now we notice that all sRTP calls fail with “white noise” in the media channel phone > asterisk.
>  
> Example 1:
>  
> Snom w/ srtp > asterisk > Yealink w/ srtp
> Both ends hear “white noise”
>  
> Snom w/ srtp > asterisk > Gigaset w/o srtp
> Snom hears Gigaset, Gigaset hears white noise.
>  
> There have been no other changes to the setup, SIP.conf  specifies
>  
> transport=tls
> encryption=yes
>  
> for the sRTP phones.
>  
> Asterisk is linked to libsrtp 1.4.2.
>  
> Here is the log (that imho looks good):
> \[inline log removed\]
