[Kamailio-Users] sems/openser13x/mi_datagram with quotes

[Daniel-Constantin Mierla]

Hello,

can you get the packet sent via mi_datagram? if you use udp inet socket 
in mi_datagram you should be able to get it with network sniffer/ngrep. 
Hope sems support net datagram socket as well.

Thanks,
Daniel
