Using windows is ok,why not using in linux? about red5phone HOT 7 OPEN

Because System.getProperty("user.dir") returns a different value when you start 
from 
wrapper and when you run from any other folder.

thanks for your reply,
but i had modified the code of SipUser.java and Asao2Ulaw.java,
String appPath = System.getProperty("user.dir");
  System.out.println("apppath="+appPath);
  configFile = appPath + "/webapps/sip/sip.cfg";

but the red5phone project can not listened the sound,

if i started the server from [red5]/wrapper,all is ok.

why?

Hi,
u need to recompile the your asao2Ulaw file in webapps/sip/assets/condec and 
set the
executable permission for the file

i have the same problem... How to recompile de asao2Ulaw?

Most times you don't have to recompile (atleast not for CentOS). Just make the 
file 
asao2Ulaw executable (chmod 755 asao2Ulaw).
