This is normal because the switch from clear to secure can happen
quickly on one end or the other and you'll have a few packets that get
thru before one end is ready... nothing to be worried about.

After ZRTP negotiation is complete (the ZRTP state machine has

2009-05-29 16:43:19 [DEBUG] switch_rtp.c:538 zrtp_logger() [zrtp
protoco]:
ERROR! Decrypt failed. ID=14:DH s=SRTP authentication failure (RTP
size=172
ssrc=2760088424 seq=53043/53043 pt=9)
They all have a time stamp of shortly after the end of the protocol
negotiation.
Is this normal, or a sign of trouble?
The call itself is fine, and ZRTP does not leave the secure state
until the
end of the call:
2009-05-29 16:43:30 [DEBUG] switch_rtp.c:538 zrtp_logger() [ zrtp
engine]:
STOP STREAM ID=14 mode=DH state=SECURE.
Are others seeing similar behaviour?
