Installing and Operating the SoftIPT
This bulletin explains how to install and operate the Toshiba SoftIPTTM. It also discusses how the SoftIPT
will work on wireless 802.11 networks.
The SoftIPT is a software phone client that runs on wired or wireless laptops, tablets and desktop PCs with
the Microsoft® Windows XP® operating software.
The SoftIPT enables true mobility with access to voice mail, programmable feature buttons, and a directory
that works with Microsoft Outlook® 2002. And because it’s wireless, you can access Internet services on
the same PC.
The main SoftIPT GUI is shown below.

The SoftIPT works with the Strata CTX100-S, CTX100 and CTX670 telephone systems with CTX R2.1
MG020 or higher.
SoftIPT operation requires a wired or wireless 802.11 connection over the IP network (Internet, WAN,
LAN, etc.) to the CTX BIPU-M2A or BIPU-M1A PCB with firmware version 07e or higher IP interface.
The voice communications uses the MEGACO+ protocol for call control signaling and RTP for voice
The SoftIPT can work on wireless 802.11 networks (see “Application Notes for Wireless 802.11
Networks” on page 9 for more information).
A user can install the SoftIPT on a laptop, tablet or desktop PC at the same time, but each should have a
unique station ID and license. The SoftIPT works with desktop or laptop PCs with Windows XP, or higher,
operating system (OS).
Access points are required for wireless systems. Customers must supply their own access points and
headphone/microphones. The SoftIPT requires the use of a headset. Without the headset, the far end of the
conversation will hear the echo caused by the laptop's built-in microphone picking up the output of the
The SoftIPT Graphical User Interface (GUI) has fixed and flexible buttons. Fixed buttons cannot be
changed (Intercom, Mute, Voicemail, Directory, Settings, Call Log and Help). Flexible buttons can be
assigned different features and labels.

Application Notes for Wireless 802.11 Networks
Application Notes for Wireless 802.11 Networks
The Toshiba SoftIPT™ works on wireless 802.11 networks. However, current access point technology
does not provide for the management of quality of service over the wireless network, which can result in a
few observable degradations in voice quality.
Our objective here is to describe these issues for the network engineer, and offer some recommendations.
As the technology evolves, and the knowledge base grows, other problems and solutions will emerge,
hence the network engineer is encouraged to search out other sources of information, from the specific
access point manufacturers or from experts in the 802.11 wireless industry.
Possible problems and their implications are:
1. Dropped packets may occur due to RF signal strength, especially as you get further away from the
access point. When small amounts of packet loss occur, you will notice a popping or clipping sound.
With larger amounts of packet loss, gaps in the conversation will occur. This is very similar to the
behavior of digital cell phones in the same situations. The best way to deal with this is to design the
wireless network for good coverage where it is needed.
2. Dropped packets may also occur due to excessive traffic on the wireless network. With multiple
devices accessing data through the same wireless network, current access points do not have a method
for prioritizing voice packets over data packets so when data applications create more traffic than the
wireless bandwidth can sustain, voice packets may get dropped. In addition, access points do not have
a mechanism for limiting the number of simultaneous sessions. In our lab we find that up to seven calls
can take place simultaneously on a single access point. This number will vary depending on the access
point, the RF environment, and any other activity in the wireless environment.
3. When one terminal is in a poor signal area for the access point that it is associated with, the access
point may automatically reduce its data rate in order to achieve better communications with that
terminal. This new data rate affects communications with all terminals, which will reduce the number
of simultaneous calls the access point can support. Network engineers should consider whether they
want to disable the Auto TX Data Rate Feature.
4. Disconnected calls will result if you move too far away from the access point, or generally are in a
poor signal strength area. With current 802.11 wireless technology, when a terminal can’t
communicate with an access point, it will disassociate with it. This appears to the phone application as
a loss of the network, and the phone application disconnects. Even if you quickly move back into range
of an access point, it will take several seconds for the 802.11 terminal to detect and re-associate with
the access point.
5. Wireless networks can only get so large, before you have to break them up into multiple subnets.
Somewhere between 256 and 1000 nodes is where networks begin to need to be broken up into
multiple subnets. When multiple subnets are employed, the call will get dropped as the terminal gets
out of range of its subnet. But the terminal can reestablish its call after associating with the new subnet.

Application Notes for Wireless 802.11 Networks
Wireless Recommendations
Follow these recommendations when using the SoftIPT on a wireless network.
• Ensure that no more than seven SoftIPT clients are working through a single access point at one time.
• Engineer your wireless network so that there is good signal strength everywhere wireless terminals will
be used.
• Use the ping program to test your wireless network. In Microsoft® Windows® perform the following:
1. Select Start > Run.
2. Type command, click OK.
3. At the prompt, type ping –t –l160 –w250 (BIPU IP address, such as
and press Enter.
This starts the ping program and sends packets to the BIPU. –l160 makes the packets the same size
as a 20msec. voice packet, and the –w250 says if there is no response in 250 msec., then the packet
dropped. Periodically you can press <Ctrl><Break> keys and see the packet loss statistics. Packet
loss ratios of 1% or less can be considered acceptable This tool provides quantitative results that can
be used when trying to engineer the wireless network.
• Employ a channel allocation strategy. 802.11b supports multiple data rates, from 1Mbps up to 11Mbps.
At 11Mbps – the objective of most networks these days, access points that are less than five channels
away will interfere with each other. This would mean that access points must be on channels 1, 6, or 11.
Some wireless network engineers have suggested that using channels 1, 4, 7 and 10 would provide a
very important fourth channel, and have minimal interference.
• Check your environment for other access points and other equipment operating in the 802.11 band.
There are many programs available that will allow you to identify access points within reach of the
terminal running the program. One example is Network Stumbler (this is not an endorsement or
recommendation of a particular product). Also consider that some cordless phones operate in the same
2.4GHz band as 802.11b.
To get the best use from your SoftIPT, consider the following tips.
• Use a headset with an attached microphone to provide good call quality and privacy. If you don’t use a
microphone/headset, the called party will hear an echo.
• When you are not wearing the headset, unplug it so that you can hear the phone ring. When the headset
is plugged in, you can only hear ringing through the headset.
• Use Microsoft Outlook 2002 to create contacts. The SoftIPT does not work with Outlook Express.
• Dialing tips: When you click or select buttons on the SoftIPT, you will not hear button tones. Also, you
must use the SoftIPT directory, keyboard or dial pad buttons to call another number. The SoftIPT does
not recognize numbers that you “copy” and “paste” onto the screen.
• If you minimize the SoftIPT, incoming calls “pop up” the SoftIPT to the foreground. If you want the
SoftIPT to “pop up” for incoming calls, always minimize it after each call.
• The SoftIPT disconnects immediately after the called party hangs up. If you select the +DQJXS button
and it turns back to the &DOO button, it means that the other party disconnected first.
• The &RQI button works the same as the &QI7UQ (Conference/Transfer) button on the DKT/IPT
• You can make a Windows “shortcut” and add it to your program menu or add it as a Quick Launch item
using the standard Windows method. The SoftIPT application does not automatically do this.
• When you exit the SoftIPT, any Call Forwarding that you set also turns off.

Installing and Operating the SoftIPT
Tested Platforms
• Make sure that you are running only one version of the SoftIPT. If you click on the shortcut icon or start
the program while you are already running it, another SoftIPT application will open. If you see
“Searching BIPU...” or “Can’t Register SoftIPT” click the close button to make sure that there isn’t
another SoftIPT running.
• If you are on a SoftIPT call and you are viewing the Setting window, select Cancel to exit the Setting
window. Avoid selecting OK during a call, since it will reset the SoftIPT and the call. The application
will operate with the new Setting information after you start the SoftIPT again.
• The Call Log does not record calls that have a name associated with it. It logs calls that are stored on the
Strata CTX as a number.
• For the SoftIPT, configure the Strata CTX BIPU PCB for G.711 CODEC at 20msec. (40msec. voice
packet transmission interval is not supported and G.729 is not supported.)
Quality of Service statistics are not available on Strata CTX for the SoftIPT.
