Summary:                    Hangups are not recognized when using IAX2
encryption
Description: 
When activating encryption on an IAX trunk link via "encrypt=aes128" the
call performs normally until one of the parties hangs up.  On the Asterisk
server which performed the hangup, it appears to hang up normally.  On the
other Asterisk server, you get a bunch of these in the log:

[Oct 16 06:37:28] NOTICE[3144]: chan_iax2.c:7020 socket_process: Packet
Decrypt Failed!
[Oct 16 06:37:28] NOTICE[3149]: chan_iax2.c:7020 socket_process: Packet
Decrypt Failed!
[Oct 16 06:37:28] NOTICE[3147]: chan_iax2.c:7020 socket_process: Packet
Decrypt Failed!
[Oct 16 06:37:28] NOTICE[3145]: chan_iax2.c:7020 socket_process: Packet
Decrypt Failed!

for about 30 seconds, finally followed by:
[Oct 16 06:37:27] WARNING[3148]: chan_iax2.c:2049 __attempt_transmit: Max
retries exceeded to host 10.250.4.10 on IAX2/mountainview-4 (type = 6,
subclass = 11, ts=10013, seqno=3)
    -- Hungup 'IAX2/mountainview-8'

I also seem to sometimes get the packet decrypt errors when DTMF digits
are transmitted (can't reproduce that one all the time though).

I've tried it with both trunk=yes and trunk=no in the iax.conf on both
ends with no difference.
