Hi, according to the doc: 1.5.9. rtpproxy_retr (integer) How many times nathelper should retry to send and receive after timeout was generated. Default value is “5”. So imagine this configuration: modparam("nathelper", "rtpproxy_tout", 2) modparam("nathelper", "rtpproxy_disable_tout", 60) modparam("nathelper", "rtpproxy_retr", 10) Let's imagine that the RtpProxy servers crashes and is down for 1 day. Does this configuration mean that the rtpproxy server will NEVER be contacted again by nathelper module since 60x10 seconds < 1 day? Thanks. -- Iñaki Baz Castillo &lt;ibc(a)aliax.net&gt;
