Hi,

I'm not sure why - but is is happening that my Freeswitch is going down with the error:

2014-02-27 11:01:50.289493 [DEBUG] sofia.c:1495 nua_i_outbound: unknown event 8: 101 NAT detected


What can cause the issue? 
Maybe somebody had this issue? I was trying to find - but can not...

Thanks in advance for help

Michal
