service that allows you to connect to 
other Skype users. The software for this 
can be downloaded from their Web site. 
It took just a few minutes to install it on 
my computer. Once you have installed 
it, you need to set up a call list of other 
users. So you have to contact people 
that you call frequently and have them 
install the Skype software. From that 
point on, it becomes much like instant 
messaging. If the person you are calling 
is on-line, you can connect and talk to 
them. Otherwise, they have no way to 
know that you are calling. The reverse 
is also true if they want to call you. The 
minimum hardware you need for this 
are speakers connected to your sound 
card and a microphone. You can also 
use a headset with a built-in microphone. 
It is also advisable that you have a 
broadband connection, either cable or 
DSL. In my testing of it, once I had a 
connection, the call was quite clear with 
no background static or other problems. 
So what do you do if you have Skype 
and want to call someone who doesn’t 
have Skype? You can get SkypeOut 
that allows you to call any phone 
number anywhere in the world for about 
2¢/minute. After you install the 
SkypeOut software you buy credit on 
their Internet site, which you can then 
use for your calls. Some reviewers have 
had sound problems with SkypeOut. I 
have not tested it. 
There are other free services 
available as well. Free World Dialup is

This is a quote from their Web site: 
“FWD allows you to make free phone 
calls using any broadband connection 
with devices that follow Internet 
standards. This can be a ‘regular’ 
telephone connected to a packetizer, an 
IP Phone, or any number of free soft- 
phones (software for your PC or PDA).” 
In order to use the system you need to 
download and install the software. Then 
you obtain a phone number from FWD. 
The hardware you need is an SIP 
compatible ATA adapter that you 
connect to a network router that 
connects to your modem. You can then 
connect any telephone to the jack in the 
ATA adapter. Now you’re ready to dial 
any FWD user anywhere in the world. 
However, you cannot dial a regular 
PSTN phone from this system without 
purchasing time from another VoIP 
provider. The advantage of FWD over 
Skype is that your computer doesn’t 
have to be on to receive calls. Your 
phone will ring just as it did when 
connected to the PSTN phone system. 
There is another advantage to FWD. 
This system uses the Session Initiation 
Protocol (SIP) standard. This allows 
FWD users to call others who are not 
member of FWD but are connected by 
a different SIP compatible service. Other 
free services currently using the SIP 
standard are IPTEL.org and 
SIPPhone.com. Skype does not adhere 
to the SIP standard. 
Now we get to the services that 
charge a monthly fee. These providers 
furnish an SIP compatible ATA adapter 
and in some instances the router for 
your telephone connection. This list 
includes companies like AT&T 
(CallVantage), Verizon (VoiceWing), 
Packet8, VoicePulse, and Vonage. Of 
these, AT&T and Verizon are the most 
expensive. Several of these providers 
are preparing wireless units that will 
allow you to connect through any WiFi 
hotspot. Vonage has announced that 
they expect to have a wireless unit 
available by mid-summer 2005. That 
means you could make and receive calls
