  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
