Hi,
can you draw your network scenario (just where is SER, SIP phones and NAT 
devices in the network) ? It'll be easier to see the problem.
Since you run SER behind NAT (am I right?)  nathelper checks for private 
addresses {RFC1918) and so the logic of ser.cfg is not then appropriate.
Can you send your ser.cfg? Have you read at onsip.org the getting started 
document?

Next time catch your SIP messages on the server by:
ngrep -d any -W byline -O /tmp/trace.log port 5060
or
tcpdump -p -s 0 -i any -e port 5060 -w /tmp/trace.log

 I've opened port 8000/8001 on my router ..

I've installed Portrptr to monitor wich ports are used by 3cx Phone (it 
says 5062 5063).
I've opened 5060 to 5070 udp) too.
Nothing has changed : no voice.

I've tried XLite : same thing , no voice.

I've tried to make a call from my Lan where Ser is installed to an user 
outside and he can hear me but I can't hear him.

If I enstablish a call from an outside user to another outside user .. no 
voice at all!

I attach X-Lite log for this case:

What can I do now ???

Yes you do. RTP (for voice and video) protocol normally uses ports
8000 for media transfer and 8001 for media control. If you are using
X-lite, then port 8000 is used definitely. A client like eyeBeam, may
choose from range of ports (i dont really know which exactly, but I
always see ports in the range of 6000-7000). And Skype, for instance,
can use ANY port available.

Anyway, you can monitor ports <= 1024 and open the rest. Those are
well known and they are the target. There are some ports > 1024 that
Windows uses for it's services and you might want to find our what
those (because, i dont really know :) are and monitor them as well.

Good luck.

Do I have to open other ports ?
