Summary:                    Recording speed too fast (running BRI B410P)
Description: 
Hi,

I have been asked by Digium support to raise a bug against Mixmonitor for
making corrupt recordings in the latest version of Asterisk (1.4.21.1 and
1.4.21).

The bug does not appear when running 1.4.19.2 (with or without the latest
Zaptel drivers).

The recordings are playing back at high speed and with very bad quality.

I'm not the only person seeing this issue:
http://forums.digium.com/viewtopic.php?t=20985

Someone on the forum claims this bug has previously been raised and fixed
but sorry I could not locate it in Mantis.

Just to note I have tested the original WAV files prior to converting them
to MP3 and the issue remains.

The audio on the call itself is near perfect.

There are no errors in the logs / on the console.


Hardware:
  Digium B410P card on BT ISDN2e lines (UK).


Example Command:
   [Jul  3 11:06:20] VERBOSE[29391] logger.c:     -- Executing
[s at macro-record:19] MixMonitor("mISDN/11-u10",
"/tmp/03072008-110620--IN.wav||/usr/local/bin/wav2mp3
"/tmp/03072008-110620--IN.wav" "03072008-110620--IN.mp3" "1215079580.4" "0"
"X"") in new stack


If anyone is kind enough to look into this issue but doesnt have access to
a BRI setup then please let me know and I can provide remote access to a
server that does.


I could be incorrectly assuming this is related to BRI as I would have
thought this issue would have been found already if it happened on T1/E1
lines.  I do have access to an E1 line although it will take me a little
time to update a server and test.  Please let me know if this would be
helpful.


Thanks for any help.

Add a tolerance period for sync-triggered audiohooks
so that if packetization of audio is close (but not equal)
we don't end up flushing the audiohooks over small
inconsistencies in synchronization.

Related to issue http://bugs.digium.com/view.php?id=13005, and solves the issue
for most people who were experiencing the problem.
However, a small number of people are still experiencing
the problem on long calls, so I am not closing
the issue yet
