Hi Benny, Yes, thats true ,i checked that my arm toolchain does not have getifaddrs() function and thats the reason it is not recognizing the hostname and the host ip addrs. Could u please tell which arm toolchain has this function. or can i insert getifaddrs() function in our pjsip application and run it. will this work?
