Here is a shell script I use for appending audio files, I guess I had to
do hard way since I've used sox for a long long time.
I call it soxcat8 ( have various versions for different encoding options )
#!/bin/sh
sox $1 -r 8000 -c 1 -s -w /tmp/$$-1.raw
sox $2 -r 8000 -c 1 -s -w /tmp/$$-2.raw
cat /tmp/$$-1.raw /tmp/$$-2.raw > /tmp/$$.raw
sox -r 8000 -c 1 -s -w /tmp/$$.raw $3
rm /tmp/$$*.raw
So vi soxcat8 , and paste, save and chmod 755
Then just soxcat8 in1.gsm in2.gsm out.gsm
Hope this helps.

Ah, it's an old version of sox, they've apparently changed the command
syntax. I just checked an old Fedora Core1 system, and it doesn't look
like it supports concatenation (as far as I can tell from the rather
cryptic manpage).
On debian (with sox 12.17.9), it's the syntax I described, as is another
fedora system where I built it from source.
What I mean by simultaneously with soxmix is that the audio will be mixed
together so that you hear both 'thousdandth', and 'through' at the same
time, rather than one after the other.

How do you mean by simultaneously in your comment after joining the files?
soxmix will mix two or more files together so that they will play
simultaneously,
It both input files becomes one file after soxmix, how can the individual
files still be play simultanously?? May be I got the wrong end of the
stick.
thanks,
Richard

Could you clarify "did not work"? As regretably, you're mistaken, the
command and syntax is:
sox sourcefile1.gsm sourcefile2.gsm destination.gsm
It might be that all the dashes in your filename are confusing the
commandline parser, and trying to use them as options...
soxmix will mix two or more files together so that they will play
simultaneously, which I don't believe is what you were asking for.

Hi Simon,
I tried using 'sox' to join the files but it did not work.
Having looked around, I think you meant 'soxmix' rather than 'sox'
Thanks,

Thanks Simon. Regarding the normalization. I tried it with a windows
tool
but it could not even read the wav file generated by sox.
I will try the tool you suggested.
Thanks,
Richard

That sort of work would happen outside of asterisk using tools like
'sox', and 'audacity'.
For example, with sox you can concatenate files like so:
sox 1-for-am-2-for-pm.gsm thanks-for-calling-today.gsm output.gsm
Normalization would happen outside of Asterisk, I'm not sure how it
would
be done from the command line with sox, though it's easy to do in
Audacity (Effect -> Normalize).

Hi,
There are a whole bunch of .gsm, .ulaw, .wav files in
/var/lib/asterisk/sounds/ within asterisk.
Is there any ways to create a custom recording by concatenating
these
available files?
Say 1-for-am-2-for-pm.gsm + thanks-for-calling-today.gsm +... to
make
up
a
custom sentence to be played back to the callers.
Also, I tried to converting a gsm file to wav format but end up
with
very
low volume - too low it's not usuable.
Any ideas on how to normalise a wave file in Asterisk?
Thanks in advance,
Richard
