[Kamailio-Users] Nathelp module Option message Empty - sr-users

1 Jul 2009


      Hi to everybody,
I have an issue with the nathelper module and openser 1.3.4 . Basically 
I want generate the Option message after the registration of a client, 
but the server generate a UDP message with the correct ip and port but 
empty.
Below the openser.cfg file and as attachment a pcap file where you can 
see the registration message and the UDP message empty.
Any clue? With the same configuration in another enviroment I don't have 
any issue
Kind Regards
Matteo
