[Users] OpenSER as load balancer for several Asterisk servers

[Edoardo Serra]

Hi guys,
         I solved the problem !

I had ip_conntrack_sip and ip_nat_sip compiled in the kernel (not as a module)
It seems like a bug somewhere in those modules

I'll setup a test environment and keep you informed !!

Tnx again for help

Regards

Edoardo
