As most of you know SkypeOut is free until the end of 2006, and using 
headsets is all nice and fun, but I know I'd rather use a real phone.
Cordless or otherwise, here's a way to use your ATA to dial out for the 
time being.

>>List of things you'll need:

1. ATA
2. Axon PBX 
(free @ http://www.nch.com.au/pbx/index.html )
[comes with a lot of extra stuff, but you don't have to install them so just 
uncheck the boxes.]
3. Uplink's Skype to SIP Adapter software
(free @ http://www.nch.com.au/skypetosip/index.html )
4. Computer running Windows
5. Skype 

>>Few things to note:

The adapter software is buggy, so when it stops working occasionally you'll 
just have to restart it as needed.

>>Asterisk Conf from mo0
In /etc/asterisk/sip.conf
[uplink]
type=friend
username=uplink
secret=fykfhqrc
host=dynamic
context=skype-in

And in extensions.conf

exten => _7.,1,Dial(SIP/${EXTEN:1}@uplink)

**Kurced (thanks to sev) Note: you need to have a "+" to dialout 
using the free skypeout as below** 
exten => _7.,1,Dial(SIP/+${EXTEN:1}@uplink)

To dial out, and a new context for incoming calls:

[skype-in]
exten = s,1,Dial(SIP/sipura1)

>>Steps:

<<1.
Set up your ATA to connect to an extension on Axon PBX using the web 
interface.

You can find pre-made extensions in the admin web interface of Axon as 
well as the ability make your own.

<<2.
Configure Uplink to connect to the PBX (Axon)

From the company's knowledge base:
http://www.nch.com.au/kb/10034.html

How do I configure Uplink with Axon?
Make sure you install Axon first, and then install Uplink on the same 
computer.

Instructions:

1. In Axon: Create a new External Line using these details:

Line Name: uplink
Server: [blank] (blank = itself I assume)
ID / User Name: uplink
Password: fykfhqrc (default line for Uplink Ext. 196)
Incoming calls ring on: [nominate an extension or group you would
like to ring when a call comes through from Skype]

Save these details.

Now go to the properties for your "Default" dialing plan. You need to
decide here what prefix needs to be dialed in order to ring out through
Skype from SIP. Our suggestion is to use the existing "9" prefix. So
where it says "if number starts with" and "9" in the second dial rule, 
click the edit button for that dial rule (see on the right side) and 
change the "dial on line" to "uplink".

2. In Uplink: Uplink will detect for the presence of Axon and 
automatically setup the SIP line for you. If you go to Settings -> SIP 
tab you can verify that the following details are present:

Display name: Uplink SIP2Skype Converter
SIP number: uplink
Server: localhost
Password: fykfhqrc

In Settings -> General tab, look at the "Dial Options" box and 
ensure the option "When SIP calls" is set to "Use the dialled number" 
and the field "When Skype calls SIP" says "uplink".

Save these changes, and then restart Uplink.

After Uplink is restarted, observe the Axon logs and you will see 
a log message appearing saying something like "External Line Skype is 
at: sip:skype@127.0.0.1:5070".

That's it, you can now test out your system.

Things you need to check now:

1. Uplink, Skype and Axon should all be on the same computer.
2. Axon should be running on local port 5060. You can see this when 
you start Axon and look at the second line in the logs, it will say "SIP 
Private IP is ..." and it will list your private IP and local port. 
When someone dials your Skype number, it will go through Uplink and 
then Axon will contact whatever extensions you told it to ring. 
And to dial out, simply type prefix 9, then type the Skype 
username that you want to contact. This can be any regular Skype 
username or even a real number if you are subscribed to the SkypeOut 
service. 

<<3.
Modify the Dial Plan on Axon. (This is mentioned before by the KB 
instructions, I elaborated for use with SkypeOut.)

Go to the Dial Plan page in the admin interface webpage.
Click the little pencil and paper edit button on the side of the default 
diaplan.
Click Add Dial Rule.
Enter your desired prefix for outgoing on the Uplink line in the "If 
number starts with" box (the single digits 6,7,or 8 work nicely)
In the remove digits box, enter the numbers of digits in the prefix, if 
it was 678, then 3, if it was just 6, then the remove numbers is 1.
In the prepend put +1 (for dialing in the US, if you plan to use 
SkypeOut to Canada, then just put +), this is needed by SkypeOut.

If you've done everything correctly, then you should be able to dial 
out by using 6-xxx-xxx-xxxx.

>>Troubleshooting:

If you can't dial out using your ATA (you hit a couple numbers and then 
it gives you an off-hook sound like mine did), take a look at the ATA's 
dial plan/digit map. I tried a lot of these and found that the simple, 
x. , worked as long as I pressed the termination digit for my ATA. 
(I use a Linksys RTP300)

Network issues: Such as port forwarding and such, you'll have to figure 
out yourself if it's needed.

>>Extra fun stuff:

Using Axon you can set up other external lines and ways to dial out on those 
lines. As an example you can set up an FWD line with an IPKALL DID. 
So you've got PSTN termination incoming and outgoing. Just add the external
line, set it up to ring on your ATA's extension, and add another dial rule 
for outgoing FWD calls.
