Hello,

I don't really need the version 8 firmware, but I install it because it 
is the most recent...

The SIP trace of the SNOM indeed does not show any answer to the 
REGISTER being sent (the SIP trace consists of only REGISTER-statements...)


I have no STUN/ICE settings filled in.

Is it possible I need STUN/ICE for the Snom 320 but not for the Zoiper 
softphone ???

The strange thing in this story is : Snom 320 receives no 200OK, but 
registration with the Zoiper softphone on a computer on the same LAN 
(connected to the PC port of the SNOM) works fine !!
