[Serusers] nathelper doesn't ping registered users

[Tomasz Zieleniewski]

HI,

I have the following nathelper settings:
modparam("nathelper", "natping_interval", 20)
modparam("nathelper", "ping_nated_only", 1)
modparam("nathelper", "rtpproxy_disable", 1)
modparam("nathelper", "tcpping_crlf", 1)

But i cant see any udp packets being sent to registered users.
Please point me what did I miss.

Best
Tomasz
