Easy way is with PFTP, part of the PuTTY suite.
Free for the taking  here, assume you want to run on your Windoze machine:

Another useful tool for audio file conversions, also free or more 
features for a small fee, is WavePad

gsm format sounds OK and takes up little space.
You need to make sure the sound is in the correct sample rate to please 
Asterisk
Asterisk expects the sound files to be in /var/lib/asterisk/sounds

Remember you only have a total of 256 Meg of flash - 64 in the boot 
partition and the rest for the keydisk and sounds.
The web interface is an easy way to check up on your storage.
>   Then I'll look into FXO and/or appropriate interface hardware to allow attachment of external hardware, as I don't believe standard FXO boxes will allow me to interface the kind of circuits I plan to use to implement my "plastic intercom" interfaces to Asterisk.  
One easy solution, depending on the number of ports is the Cisco 3810 
which sits on your LAN and communicates via SIP to Asterisk They are 
considered end of life and show up on eBay from time to time.
John Jones is the resident Cisco 3810 expert!
> The "dial-window-call-button" circuits will probably be the most difficult to design since they will also need interfacing to FXO-type circuits,but I suppose it'd be possible to use FXS to interface them also (but then there's the problem of the ring-cycle, which I don't want on my Plastic system -- I want the ringing/ringbacktone to come FROM that Plastic system, and allow the caller to use DTMF directly into the Plastic interface, and use the '#" key to send the approx. 9-volts required to generate theringtones which are produced inside of each phone internally both for ringback-tone thru the line at reduced db levels, and at AMPLIFIED levels out thru the phone's external mic/speaker).

Once you get all of this working, you'll have to explain in detail.
>   An additional variable tone-oscillator will be added to give the simulated ring effect that was prevalent when we attached more-than-one phone to one line back in the '70's and early '80s; the effect was very unique when the right audio freqs. were combined to produce a "warble" ring effect which was different in tone/freq.division for each phone on the system; some sounded like a high-pitch tone with 15-Hz. ring mixed in, some sounded like a 30-Hz. or higher ring voltage with a 500 or 600-Hz. tone mixed, and some were simply very strange effects WITHOUT description.  I believe an extremely low minute voltage was placed on any of the phone's lines when they would go off-hook, so a transistor circuit would be needed for each of the extensions on the Plastic system to act as a line-relay of sorts.

Also when you get this working you will need to supply detail

> I find that this project will be very challenging, but no matter how long it takes, I want to see it eventually come to fruition, even if it means paying for some of the design help, as my knowledge of transistor design is very rusty now, since my Electronics Tech. training at school over 25 years ago.
> In the meantime, I'll post some of the recordings of our funtimes with the plastic phones on the various numbers in my pool, so that those interested can get some idea of how they worked and maybe offer suggestions, (if not also for amusement, which I think is the aspect of the recordings most ppl will benefit from, lol).
OK!

> Meanwhile, 782-3729 is presently active, along with some other numbers for the standard * tests.  I will update my directory as I add recording files to different numbers.

If you look through extensions.conf, you will see a few sample sounds 
from the phonetrips and other web sites.
A standard package I have included on many of the machines I have set up 
for others.
