asterisk users - Mar 2003 - RE: [Asterisk-Dev] Several patches, including recording and music -on-hold

Hi Wade,

Thanks! The call recording is pretty easy to use. There is a new resource
providing call monitoring, and it registers these three applications and
manager commands:
- Monitor
- StopMonitor
- ChangeMonitor

Monitor is used to start recording a channel. It takes an optional filename
as a parameter. If no filename is supplied it determines one on its own,
based on channel name. Two files are created, one for each direction. Files
are created under /var/spool/asterisk/monitor. Another optional parameter is
used for file format, it defaults to "wav".

StopMonitor is used to stop recording. Note that recording stops when the
channel hangs up cleanly too, so it is not needed to use that unless you
want to record only a specific section of the call.

ChangeMonitor is used to change the filename recording is done, while
recording is going on. This change physically takes place after recording
stops.

The manager command versions take an additional channel name option.

Some examples:

- Application version:
exten => _4XXXXX,1,Goto,2
exten => _4XXXXX,2,Monitor,pcm|testfile
exten => _4XXXXX,3,Answer
exten => _4XXXXX,4,Queue,hpoutgoing|15
exten => _4XXXXX,5,Goto,hpbye|1

- Manager version (in this example a client attached to the manager port
sees the channel queue event and sends a message to start monitoring)
exten => _1XXXXX,1,Goto,2
exten => _1XXXXX,2,AbsoluteTimeout,3600
exten => _1XXXXX,3,Answer
exten => _1XXXXX,4,Queue,hpoutgoing|15
exten => _1XXXXX,5,Goto,hpbye|1

Thanks!

I added this to an iaxtel extension I had, and it worked great!

Was:

[iaxtel]
exten => _91700NXXXXXXX,1,StripMSD,1
exten =>
_1700NXXXXXXX,2,Dial,IAX/Zebble:mypassword@iaxtel.com/BYEXTENSION@iaxtel


Now:

[iaxtel]
exten => _91700NXXXXXXX,1,StripMSD,1
exten => _1700NXXXXXXX,2,Monitor
exten =>
_1700NXXXXXXX,3,Dial,IAX/Zebble:mypassword@iaxtel.com/BYEXTENSION@iaxtel


When I dial my iaxtel number from my extension on channel Zap/15, I get two
files recorded in /var/spool/asterisk/monitor:

Zap-15-1-in.wav and Zap-15-1-out.wav and they sound fine.

When I dial again, it overwrites the same two files.  A nice option would be
to append to the current files (with an audible *break*), or create another
unique filename (timestamp?).  I realize the latter could be done with
variables and the former could be done with AGI, but it might be nice to
have it part of the Monitor resource?

It would also be great to see only one file.  A mix can be done later, but
it looks like the two files start and stop at different times so it would be
pretty tough to sync the two files up after the fact.  Another option might
be a logfile with start/stop times of each file to assist with syncing?  The
times would have to be pretty accurate (at least within milliseconds) to
work well...

I haven't tried it yet, but when recording a meetme conference, there are
probably a set of files for every incoming channel.  Syncing those up into a
single WAV could be a serious nightmare.  ;)

And don't get me wrong.  I ain't complainin', just thinkin' out
loud.  :)

Thanks again Mahmut.

They are merged with CVS now.
