Hi, I have set up the asterisk in Redhat 9 with kphone, kphone is successfully registered under asterisk console.....so i had some tests on the extension......but there were messages saying that something(probably .gsm files) were being played, but i heard nothing.....there were also some warning messages from the asterisk console(when i launch it asterisk -vvvc) saying that ERROR:sound device currently not available(some sort like this).....may i know what's wrong? 1)do i need to install any codec in order to solve this problem? actually i have downloaded the iLBC source files...but do not how to install it...."make install", "./configure" cannot be executable....so any ideas? 2)Actually im planning to set the asterisk under cygwin? can this be done? can asterisk be operated under cygwin? thanks alot --------------------------------- Do you Yahoo!?
