[Serusers] Mediaproxy sample

Hi all. Can anyone send me I simple ser.cfg file with mediaproxy support or take a look at mine which is below ? I have been using rtpproxy and nathelper and now I have changed to Mediaproxy. I have substitute the functions but it does not work properly and it hangs when I try to establish a session between 2 UAs and I am almost sure that is my ser.cfg (attached). Thanks in advance: Kiko ser.cfg ===== check_via=no # (cmd. line: -v) dns=no # (cmd. line: -r) rev_dns=no # (cmd. line: -R) port=5060 children=4 fifo="/tmp/ser_fifo" listen=193.145.235.165 # Defino lo alias siguiente para identificar si la llamada va hacia dentro # del dominio o ambas partes pertenecen al dominio. alias="ua.es" alias="sipua.ua.es" # ------------------ module loading ---------------------------------- loadmodule "/usr/local/ser/lib/ser/modules/sl.so" loadmodule "/usr/local/ser/lib/ser/modules/tm.so" loadmodule "/usr/local/ser/lib/ser/modules/rr.so" loadmodule "/usr/local/ser/lib/ser/modules/maxfwd.so" loadmodule "/usr/local/ser/lib/ser/modules/usrloc.so" loadmodule "/usr/local/ser/lib/ser/modules/registrar.so" loadmodule "/usr/local/ser/lib/ser/modules/textops.so" loadmodule "/usr/local/ser/lib/ser/modules/auth.so" loadmodule "/usr/local/ser/lib/ser/modules/acc.so" loadmodule "/usr/local/ser/lib/ser/modules/auth_radius.so" # !!
