[OpenSIPS-Users] mi_datagram - UDP is [still] broken?

[Bogdan-Andrei Iancu]

Hi Alexander,

the mi_datagram is not broken (and never was). you can run a very simple 
test with NC (network commander):
     >  echo -e ":uptime:\n\n"| nc -u 192.168.2.1 5059

About you php code I cannot comment as I'm not a php programmer :)

Regards,
Bogdan
