For SPANDSP, i do this:

download source spandsp-20061010.tar.gz  
./configure  
make  
make install

For Asterisk, i do this

patch asterisk 1.4 with spandsp/test-apps-asterisk-1.4 branch

make clean  
./configure  
make  
make install

my extensions.conf

Asterisk crashed… Wait for 1.4 to be released and spanDSP fully updated or use 1.2.

P.S. Stop using so many punctuations!!! Ok???
