We are running asterisk with 8 port FXO. FXO connects to our old PBX (Samsung Office Serv 100).

Now we want to record all calls routed through FXO (if it was dialed to outside or comming from outside).

Here is the diagram

          |------|---------------------------------
          |      |--------------24 Lines ---------- Other clasic Phones

PRI------ | PBX |---------------------------------

          |      |
          |      |
          |      |-----------|---------|
          |      |--8 lines--|         |---------         
          |      |-----------|Asterisk |---------- 50 SIP phone
          |------|           |         |----------
                             |---------|----------

Is there a simple way to do this? asterisk share|improve this question

Are you running plain Asterisk? If so you can modify your dial plan to start 'monitoring' the channel, which will record the call.

The monitor command's documentation: http://www.voip-info.org/wiki/view/Asterisk+cmd+monitor

Just for the sake of completion, here's the documentation:

[root@localhost ~]# asterisk -rx 'core show application monitor'

  -= Info about application 'Monitor' =-

[Synopsis]
Monitor a channel

[Description]
  Monitor([file_format[:urlbase],[fname_base],[options]]):
Used to start monitoring a channel. The channel's input and output
voice packets are logged to files until the channel hangs up or
monitoring is stopped by the StopMonitor application.
  file_format           optional, if not set, defaults to "wav"
  fname_base            if set, changes the filename used to the one specified.
  options:
    m   - when the recording ends mix the two leg files into one and
          delete the two leg files.  If the variable MONITOR_EXEC is set, the
          application referenced in it will be executed instead of
          soxmix and the raw leg files will NOT be deleted automatically.
          soxmix or MONITOR_EXEC is handed 3 arguments, the two leg files
          and a target mixed file name which is the same as the leg file names
          only without the in/out designator.
          If MONITOR_EXEC_ARGS is set, the contents will be passed on as
          additional arguments to MONITOR_EXEC
          Both MONITOR_EXEC and the Mix flag can be set from the
          administrator interface 

    b   - Don't begin recording unless a call is bridged to another channel
    i   - Skip recording of input stream (disables m option)
    o   - Skip recording of output stream (disables m option) 

By default, files are stored to /var/spool/asterisk/monitor/.

Returns -1 if monitor files can't be opened or if the channel is already
monitored, otherwise 0.

And here's a sample way you can use it:

; This fake context records all outgoing calls to /var/spool/asterisk/monitor in wav format.
[fake-outgoing-context]
exten => s,1,Answer()
exten => s,n,Monitor(wav,,b)
exten => s,n,Dial(DAHDI/g0/${EXTEN})
exten => s,n,Hangup()

Obviously you'd have to make changes to my code, but hopefully that gives you a good idea.
