<html><body><p>Hello,</p><p><br></p><p>Base on my testing OPTION
pings can be sent only to UDP nated clients. So it is impossible
with kamailio to send OPTION pings to TCP/TLS nated clients? I found doc for
some version of nathelper module where the natping_tcp parameter can be
set by</p><p><br></p><p>modparam("nathelper", "natping_tcp",
1)</p><p><br></p><p>Unfortunately, this parameter cannot be used in default
nathelper module in kamailio 4.2.(doc is probably from OpenSIPS) I
would like to send OPTION pings to TLS nated and individualy
selected user agents. Does exist some possibility to do it with kamailio
4.2? If not by default does exist the possibility to compile and build
kamailio with the nathelper module mentioned above (with natping_tcp
parameter)?</p><p><br></p><p>Or does exist some other
solution?</p><p><br></p><p>Thank you in
advance</p><p><br></p><p>Petr<br></p></body></html>
