asterisk users - Oct 2008 - cdr,gsm file format

Hi

1. What is the best way to convert wav (44000 Khz) to gsm format for 
asterisk ? I;ve tried sox command but the outcome is not satisfying...The 
built-in gsm files shipped with asterisk are simply superb ..How do i create 
gsm files of similar quality ? Can anyone help me out ? if sox is the only 
way can anyone tell me the exact command ?

2. Can Freepbx 2.5 installed above asterisk 1.6.0 or trunk versions ? in 
short does it support dahdi ?

3. If i cannot use Freepbx 2.5 where will the CDRs get stored and how i 
access them for writing my custom cdr program ? i saw that there is a cdr.so 
module that gets loaded - can it help me in anyway

Thanks in advance

Sriram

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.
