Connecting to an SL1100 that IS on a Network [HAS VoIP Card]

Posted: March 15, 2014 3:20 PM

Using our Printed Instructions? This tutorial covers the Pink Chapter.

One of the nicest features of the SL1100 is its ability to be a 100% pure Voice over IP phone system.  This gives you tremendous flexibility.  Not only can you network your phone system, but you can network up to five locations.  You can have Voice over IP phones inside or outside your office, you can save money by replacing your phone lines with SIP trunks, and you can also utilize the Desktop Suite software which integrates your phone system with Microsoft Outlook.  Now in order to gain these benefits, it requires just two things.  A Voice over IP Daughterboard card, and a basic knowledge of IP Addresses. 

We’ve realized that not all of our customers are IT professionals.  That’s why we created the step-by-step video tutorial of how to quickly assign an IP Address to your phone system that is in the range of your local area network. 

The first thing we’ll need to know is the address of the local area network we’re installing the phone system onto.  We can do this by opening a command window.  So let’s click on the start menu, and where it says Search programs and files we’re going to type cmd and press enter.  Once we have a command prompt window open, let’s type ipconfig and press enter.  That’s ipconfig and press enter. 

OK, this brings up three addresses.  The first is the IPv4 Address.  This is the IP Address of the computer I’m currently using.  The second address is the Subnet Mask.  The Subnet Mask basically defines which IP Addresses are a part of my local area network.  This address we’re going to write down for future use.  So in our case the Subnet Mask is, and we’ll call this subnet mask.  The third address is the Default Gateway.  This is the address we use to talk to the outside world.  We’ll want to write this number down as well.  So in our case it’s, and we’ll label this default gateway.  

Now before we move on, let’s go back and look at that IPv4 Address again, because it tells us something important.  It tells us the address of the local area network.  The network address is the first three groups of numbers separated by periods.  In our case it’s 192.168.1.  This is the network address.  The very last number of the IP Address is the local address of the computer that I’m on, or any device plugged into the network. 

So next we need to create two new addresses based off of our network address, again 192.168.1, and these two new addresses will be programmed into the phone system.  The first will be the address of the phone system itself, or more specifically, the Voice Daughterboard card.  And the second will be used for Voice Ports such as IP phones or SIP trunks. 

In order to create two new addresses on the network, we need to first know which addresses are already being used up by other equipment.  We can do this by going back to our command window and typing arp [space] – [hyphen] the letter a, and press enter.  This brings up a list of all the devices currently on my network.  As you can see I have a couple of computers and a printer, all of which are getting their IP Addresses assigned to them dynamically from a router, or in some cases, a server, and on some networks you may see a list of devices with static IP Addresses as well.  We’re looking for the last dynamic IP Address.  In our case it’s and we’ll create the two new addresses immediately after that one.  So we’ll use for the Voice Daughterboard card, and for the Voice Ports.  I’d like to state at this time that if there is an IT Administrator onsite I would strongly recommend letting them designate these IP Addresses for you.  However, if no IT person is available, this is an easy do-it-yourself way to find out which IP Addresses are already in use on your network. 


Now that we have our list of IP addresses, we’re going to program them into the Phone System.  Now, the phone system I’m working on here is loaded with our default programming.  This default programming is pre-loaded onto every phone system we sell, and it’s full of all sorts of time savers that 99% of customers are going to ask for. So if you didn’t purchase your phone system from us, then your results might vary due to the programming currently in your system.

Also, it’s important that before entering these IP Addresses, we want to unplug the phone system from all Ethernet connections. 

Now if you’ve purchased the phone system with a VOIP Daughterboard Card, the VoIP Card will be pre-installed for you.  So, if you’ve just taken the system out of the box, I find it best to assign the system its IP Addresses before we do any other programming.  Plus, we’re going to have to power off the phone system after we enter these IP Addresses, so I recommend getting these steps out of the way up front, reboot the system, and then dive into your programming.

If, on the other hand, you’re working with an existing SL1100 phone system, and you’re installing a VoIP Card into it now, then it would be a good idea to back up the phone system’s database before changing any of these IP Addresses. 

Alright, so let’s get started….  So, again, with the phone system unplugged from ALL Ethernet connections, we’re going to go to a phone and press the speaker button…

Then press #*#*.  We’re prompted for a password.  That password is 1 2 3 4… 5 6 7 8 and press Menu.

We’ve now entered the Programming Mode.

The first programming code that we’ll enter is 10-63-01, this is the DHCP Client Mode.  Our default programming has DHCP set to YES. But in this scenario, we’ll want to change it to NO by pressing the +1 soft key under the LCD display. This turns DHCP OFF.

Press the Menu button.

Now, press the Mute key two times to back out of this program.

The next program code is 10-12-01, here we’ll see the current IP Address of the CPU card in this phone system, however, because we have a VoIP Daughterboard Card installed, we no longer need the CPU Card to have an IP Address.  This IP Address, of the CPU Card, would only come in to play if we did NOT have a VOIP Card Installed.  So we’ll want to Zero this address out.  So press and press Menu.

At 10-12-02, we’re asked for the Subnet Mask.  So we’ll refer to the address that we obtained a couple of minutes ago.  For us it’s

Press Menu

At 10-12-03 we’re asked for the Default Gateway. So again, we’ll refer to our list and enter

Now continue to press the Menu Key until you reach 10-12-09

At 10-12-09 we’re asked to program the IP Address of the VOIP Daughterboard.  This was the first address we created. So in my case, I’ll enter

And Press Menu.

Ok, now we’ll press the Mute Key FOUR times to back out of the 10-12 programming.

Now enter programming code 84-26-01.

For the Slot Number, press “0”, and then we’re asked for an IP Address.  This IP Address is going to be used for Voice Ports. So we’re going to refer to our list and enter the second IP Address we created. In our case it’s

Then press Menu to save it.

Now we’ll press the MUTE key FOUR more times to back out of programming and press the Exit Button.

On the LCD Display you’ll see that your data is being saved.

We’ve now assigned a Static IP Address to the VOIP Daughterboard, so that every time it’s rebooted, we’ll know exactly how to reconnect to this phone system.

So at this point, it’s VERY IMPORTANT to wait at least 5 minutes before rebooting this system, because even though my display has come back up, the changes are still being written to the phone system.

I’ll also remind you again, that if you’re working with a pre-existing SL1100, it would be a good idea to back up your database before powering down.

So I’m going to wait 5 minutes, power off the phone system, plug an Ethernet Cable into the Ethernet Port on the VoIP Daughterboard Card and then turn it back on.

And we’ll pick back up again.

Alright, I’ve rebooted my phone system, and now we just want to make sure that our programming changes have been updated.

We can do this by going to any phone and pressing Menu 96, then tap Menu again, and there you can see that the IP Address of the CPU Card has been zeroed out, and the VOIP Daughterboard Card has been updated with the IP Address that we created.

Let’s wrap this up by opening PC Pro and connecting to the Phone System.

Now that we’ve established and assigned an IP Address to the Phone System, we can easily connect to it using the PC Pro Software. To do this, click the connect Icon in the upper left-hand corner, then enter the IP Address that we created and assigned to the VoIP Daughterboard.  In our case –  Enter the username sltech, all lowercase, and password 1 2 3 4 5 6 7 8, then press connect.

And there we go, we are now connected to the phone system.  And because we turned off DHCP, through the phone, it doesn’t matter if this phone system is rebooted or if the power goes out, it will always retain the same IP Address.

I hope you found this tutorial helpful and good luck programming your SL1100 Phone System.
