Hello there, I'm trying to setup FreeSwitch but I'm getting this error everytime I run it..

mod_event_socket.c -> Socket Error Could not listen on 127.0.0.1:8021

Also, an error here:

mod_xml_curl.c:230 xml_url_fetch() Received HTTP error 0 trying to fetch ...

The question is, is something needed to avoid the 8021 error? I'm running Ubuntu 10.04 with ufw enabled (port 8021/tcp allowed).

Note: Googled but nothing helps

Thanks in advance
