Hello all,

In nathelper the documentation mentions two pinging types (upd 4 byte packets and stateless SIP request). Is there a way to choose between one or the other or are they both activated by default?

I have configured nathelped to ping with OPTIONS every 15 seconds.

modparam("nathelper", "natping_interval", 15)

modparam("nathelper", "sipping_method", "OPTIONS")
In addition to the OPTIONS packets that are sent every 15 seconds, there is a 4 byte packet that is sent every minute. Why does this happen and is there a way to turn it off?

This is what the ping packet sequence looks like:

time ping

0 ---> 4 byte pkt

0 ---> OPTIONS

15 ---> OPTIONS

30 ---> OPTIONS

45 ---> OPTIONS

60 ---> 4 byte pkt

60 ---> OPTIONS

thank you

George
