Hello, I can't build socket2me http://pastebin.freeswitch.org/3015 i installed this package ii libspandsp-dev 0.0.2pre26-1 Telephony signal processing library and i see t30_stats_s has really no these members. should i install other version of spandsp-dev, or have you any idea? other: i am trying to understand what the code do, and dont understand what is the purpose of local and remote ip. addr.sin_family = AF_INET; addr.sin_addr.s_addr = htonl(INADDR_ANY); sendaddr.sin_addr.s_addr = inet_addr(remote_ip); addr.sin_port = htons(remote_port); sendaddr.sin_family = AF_INET; sendaddr.sin_addr.s_addr = inet_addr(local_ip); sendaddr.sin_port = htons(local_port); sendaddr.sin_addr.s_addr is assigned twice...is it a typo? Thanks any help, Tamas
