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 --->

So what could resolve my problem?
