Chapter 1 - How does Packet8 Softalk™Work?
2
■Managed contact list - importing and exporting contacts between Softalk and other
applications
■Call history - list of received, missed, dialed and blocked calls.
■Keyboard shortcuts for most major functions
■SIP compliant
■STUN, TURN & ICE NAT traversal
■Packet8 Softalk™ supports the following audio codecs: G.711u. G.711a, G.729, iLBC
■Packet8 Softalk™ supports the following video codecs: H.263, H.264
How does Packet8 Softalk™ Work?
Instead of phoning over traditional telephone networks, Packet8 Softalk™ calls are
made over computer networks through an Internet service provider or a local area
network (LAN). This breakthrough in telecommunications is called Voice over Internet
Protocol – VoIP, or “Voice over IP.”
Calls made anywhere in the world to similar Internet-based telephones are generally
free, while calls made to traditional telephone systems can be much cheaper than
typical long-distance and international rates. Voice quality for conversations using VoIP
technologies can greatly exceed traditional telephone services.
Packet8 Softalk™ uses the Session Initiation Protocol (SIP) for session signaling and the
International Telecommunications Union (ITU) codec standards for voice and video
(G.711, iLBC, G.729, H.263, H.264).

CHAPTER 3
Using Packet8 Softalk™
The Key Pad
The Packet8 Softalk™ softphone provides an easy-to-use key pad as the main user
interface, which allows for quick access to both basic and advanced calling features.
Refer to Figure 1 below for an illustration of the Packet8 Softalk™ user interface.
Figure: 1 Packet8 Softalk™ User Interface

Chapter 3 - Before Making a Call
6
Before Making a Call
Things to Keep in Mind
Making calls with Packet8 Softalk™ is simple; there are, however, some differences
between a softphone and a traditional telephone which the user should be aware of:
1. A softphone is a computer application that must be running to make or receive calls.
2. Softphone software must login to the network before making or receiving calls. This
procedure may take a few seconds as the softphone contacts Packet8’s network.
Once the softphone’s call status reads Logged in – Enter Phone Numbe the user is
ready to make or receive calls.
3. Since calls are transmitted over the Internet, service quality may drop due to network
congestion. Although Packet8 Softalk™ includes advanced signal processing
features to mask the effect of such congestion, decreased voice quality may be
noticeable during poor network conditions. Most broadband connections provide
adequate bandwidth for high-quality voice and video. If you experience poor audio
or video quality, please see “Packet8 Softalk™ Troubleshooting” in Appendix A.
Logging In
The log in dialog will show up and request user to log in to the network by entering your
Packet8 Softalk™ number and password.
When finished entering all of the information, click Log In. If all required information is
saved, Softalk will attempt to login to the Packet8’s network, indicated by a Logging in…
message in the call status screen.
IMPORTANT When the message Ready - Your Softalk Number: 1-XXX-XXX-XXXX appears in
the call status screen, then Packet8 Softalk™ is ready to make and receive calls. If You see the
message Login failed!, then they failed to login successfully and will not be able to make or
receive calls. For such cases refer to Appendix A: Packet8 Softalk™ Troubleshooting of this
document, which includes tips for this and other potential softphone problems.
Figure: 2 Log In Dialog Box

Chapter 3 - Placing a Call

Placing a Call
As mentioned in the previous section, Packet8 Softalk™ is ready to make or receive calls
once you see the message Ready – Your Packet8 Softalk™ Number in the call status
screen.
There are several ways to enter a phone number in Packet8 Softalk™. You can click the
digits of Packet8 Softalk™’s on screen numeric keypad, or you can enter the numbers/
letters directly from your computer’s alphanumeric keyboard.
Notice that when you begin to enter a number, Line 1 is automatically selected as the
line in use for that call—as shown in Figure 3 below.
If at any point you enter erroneous digits, click the Clearbutton within the dial pad or
press Backspace button on the computer keyboard to make corrections.
When you enter a phone number, you will receive prompts for completing that number
(as shown in Figure 3). To enter the rest of the number as suggested, hit the Tabkey on
the computer keyboard to enter the remaining digits.
When you are finished entering a number, click the green telephone icon button on
screen or press Enter on the computer keyboard to dial.
As with a traditional telephone, you will hear ringing as Packet8 Softalk™ tries to access
the remote caller. At this time, you also will also see the message “Ringing” in the call
status screen. When the remote caller answers, you should hear him/her and see the
message “Call Established” in the call status screen.
