Dears;
What Jian said is the right and it worked.
But I have the following questions:
Why 192.168.10.2 is wrong and I have to use 192.168.10.0? Also, do I have to
set the localnet or it is enough to set the externip?
The IP information is called "IP subnetting" which is the basic rule
about IP address. It seems you are using a Class C private subnet so
192.168.10.2 will never be a correct "network address". (Depend on your
subnet mask, the network address could be like something else. But the
last octet 2 is obviously wrong!)
If your Asterisk is behind a NAT router/firewall, you need:
localnet=
externip=
nat=yes

From the other side, I am using Asterisk 1.8.12.0 and when I was searching in
the sip.conf, I did not find externip (so I added by my hand) and I remember
very well that before I was able to find the externip in the sip.conf, although
I am finding externadd. So why this?
One more thing, what is the difference between externadd and externip?

Dears;
It seems my service provider is requesting a
complicated settings to allow me to send from behind NAT.
What they said:
"It shouldn't matter as long as you are handling the
NAT correctly your end. We do not fix NAT so if you're
sending internal addresses in your INVITEs or SDP then
things will fail but if you're handling it correctly, we
shouldn't tell the difference".
Really, I did not understand what exactly they need.
But maybe what they need is to see my public IP address
without the private IP address (this what I understood if I
am right).
I tried to use the following in the [general] settings
in the sip.conf
localnet=192.168.10.2/255.255.255.254
externadd =196.40.164.239
I think these setting are all wrong:
1. local network should be something like: 192.168.10.0
2. Subnetmask cant' be 255.255.255.254 !
3. externip=x.x.x.x (Not "externadd")
Jian
But even, the calls are drop .. so what I have to do?
The following what I get when I enabled the sip debug:
<--- SIP read from UDP:194.0.220.220:5060 --->
SIP/2.0 403 UA behind NAT not accepted here
Via: SIP/2.0/UDP

So what could resolve my problem?
