Sox should be suitable for this, however since Asterisk 1.4 inbuilt
conversion is supported.

*CLI> help file convert
Usage: file convert <file_in> <file_out>

Why not just use what is shipped? Is there a killer feature that 1.6 or
trunk provides that the recommended versions don't support?  Although
Dahdi is now available in newer releases, it doesn't mean that legacy
Zaptel will suddenly stop working.  The Dahdi channel driver can also
present as "Zap/channel" still, so I would imagine it wouldn't cause too
many problems.  However, you would be better to seek assistance from the
FreePBX forum.

The FreePBX forum would be a better place for this, I would imagine you
will get an answer sooner.
