[Asterisk-Users] Setting up asterisk for one user in private ip NAT.

[Alex Polite]

Hi. 

I've just bought SIP telephony service from a Swedish telco.

I've managed to make and receive calls with kphone.

Now I want to set up asterisk to be able to add fancy features like
voice mail and recording conversations. But first I
have to get the basic setup right. I'm running asterisk and kphone on
the same machine, behind at NAT-router.

When I make a call (from my regular phone) to the SIP-number I get a
busy signal and I see my regular phone number in the debug output
of Asterisk. I guess that means I'm doing something right.

The problem now is that I can't get kphone or linphone to connect to
asterisk. Trying to connect from kphone to asterisk does not generate
any messages in the asterisk debug output. Non what so ever.

Which has me thinking that ip might be something with the
hostnames/ip-addresses that's not right? 

What does "bindaddr" do? I've tried changing it to my private IP but
that doesn't make any difference.


I know that I'm not being very specific in my questions but I feel
that I need some handholding here. Some tests that I can run, for
example, to find out if my Asterisk setup is kosher. So, will someone
please hold my hand in this scary land of VOIP?
