Hi all,
There’s something going wrong with my asterisk… I need to put it in a compact flash so I must safe as much space as possible. For this space saving purpose, I installed asterisk in a virtual machine which has the same kernel version, same OS, … and after that, i moved all the necesary files to the compact flash.
It works fine on the virtual machine but when i move the files to the compact flash, i get some problems with the lpc10tolin and gsmtolin codecs, which are making asterisk unable to start (illegal instruction).
In order to get rid of that messages I decided not to load that modules ( noload => codec_gsm.so, noload => codec_lpc10.so) and I got it to start. However, once I have configured all the SIP clients and all the network, when I’m trying to make a call I get the next warning messages:

Illegal instruction
which I guess makes sense if the previous modules are not loaded, but… 
Could somebody help me with these issues?
Thanks very much!!
