I find that highly likely. I'm pretty new to Asterisk.

But it does use some codec. Even if it's not the same one, there is a
piece of software that can decompress it, and you can (probably) store

I realize this cannot be done due to licensing and other considerations.
I'm just saying that the details may be wrong, but the principle stands.
