INTRODUCTION TO THE IP250D
1 Introduction to the Teledex IP250D VoIP Network Terminal
The Teledex IP250D VoIP network terminal is very similar to a modern business desk
telephone. Instead of using telephone lines, it connects to the office network in the same
manner as computers and printers do. The acronym VoIP means Voice over Internet
Protocol. The voice and control signals to and from the IP250D are entirely digital data
that is transmitted over the office data network, rather than phone lines.
1.1 THE IP250D WORKS LIKE A TELEPHONE
The IP250D functions in a manner very similar to a modern office telephone that is
connected to a PABX (private automatic branch exchange.) In this user’s guide, the
IP250D VoIP network terminal will sometimes be referred to as a “phone.”
FIGURE 1.1 – THE IP250D KEYSET
Teledex IP250D User’s Guide SIP/MGCP
INSTALLING THE IP250D
2
1.2 TWO LINES
The IP250D can handle one or two calls simultaneously, much like a standard “two-line”
analog or digital telephone. However, there is only one line (or cable) connecting the
IP250D to the network.
1.3 THE NETWORK
Instead of telephone lines, the IP250D connects to other IP phones via an Ethernet network.
1.4 THE CALL CONTROL SERVER
A specialized network server, called a “SIP server” for SIP IP phones, or a “Call Agent”
for MGCP phones, controls all of the IP250D terminals, and other types of VoIP
terminals that are connected to the network.
1.5 THE NETWORK OR SYSTEM ADMINISTRATOR
The IP250D requires configuration in order to work properly on the network. This task
is performed by a technical specialist referred to as a network or system administrator.
The network administrator will perform the configuration steps from a control station.
2 Installing the IP250D
Installing the IP250D at an office desk or workstation is as simple as installing a
conventional office telephone.
2.1 A MATTER OF SAFETY
WARNINGS mean danger to persons and possibly, damage to equipment. Whenever you
see this symbol, be careful to study the steps that you will perform, and be sure that you
understand the nature of the hazards before beginning the task.
CAUTIONS mean risk of damage to equipment. Whenever you see this symbol, be aware
of the steps that you will perform and be sure that you avoid the conditions that may
damage the equipment.
NOTES point out exceptions or additions to the information presented in a particular
section. You may want to highlight some information that you will need to remember
periodically in the operation or installation of this device.

WARNING
Teledex IP250D User’s Guide SIP/MGCP Part Number 600-0480-603
INSTALLING THE IP250D
2.2 UNPACKING THE IP250D
The IP250D VoIP network terminal package contains several components:
• The main base unit, sometimes referred to as the keyset
• A handset for use during conversations
• A desk/wall mount bracket, to support the keyset at a convenient angle on
the desk, or for mounting the phone on a vertical surface, such as a wall
• A network patch cable for connecting the keyset to the network
• A handset coil cord, to connect the handset to the keyset
• Package may also contain an optional power supply (if necessary)
2.3 CONNECTING THE HANDSET
Plug one end of the coil cord into the RJ-10 receptacle on the handset and the other end
into the receptacle on the left front side of the keyset. Place the handset into the cradle of
the keyset.
2.4 CONNECTING THE IP250D TO THE NETWORK
Warning! Risk of electrical shock! Dangerous voltages may be present on the terminals of
the network patch cable after it is plugged into the network wall jack. Connect the patch
cable to the keyset base first, then to the network wall jack.
Plug one end of the network patch cable into the RJ-45 receptacle labeled 10/100 SW on
the bottom of the IP250D keyset. Connect the other end of the cable to the network wall
jack (receptacle) designated by the network administrator.
Caution: Do not connect a telephone cord to the network RJ-45 jack.A standard RJ-11
telephone cord connector can fit into the RJ-45 jack, however there is risk of damaging the
equipment if this is done.
Note: The IP250D will not function until it has been configured and activated by the
network administrator.
2.5 CONNECTING A PC TO THE IP250D
If the office or cubicle space has only one active network receptacle, and another network
device such as a PC must share the same space, the PC should be disconnected from
the wall jack and reconnected to the RJ-45 receptacle on the bottom of the IP250D that
is labeled 10/100 PC.
!
WARNING
Teledex IP250D User’s Guide SIP/MGCP
INSTALLING THE IP250D
4
Caution: The cable from the network wall jack must be connected to the connector marked
SW, and if there is a PC, it must be connected to the connector marked PC, otherwise the
IP250D will not function.
2.6 ARRANGING THE IP250D ON THE DESK
Route the network cable toward the rear of the keyset and attach the desk/wall
mounting bracket by inserting the snap fasteners into the matching holes in the base.
Place the unit at a convenient location on the desk. Be sure to replace the handset on the
cradle and ensure that the hookswitch is properly depressed by the weight of the earpiece
of the handset.
2.7 MOUNTING THE IP250D ON A WALL
The IP250D can be mounted on a wall or other vertical surface. To do so, the desk/wall
mounting bracket should be rotated 180 degrees, compared to the desk mounting
position. Use screws (and anchors, if necessary) to match the hole pattern in the bracket.
The wall mounting clip near the hookswitch should be removed and re-installed after
rotating it 180 degrees. To remove the clip, push it firmly toward the hookswitch.
The clip will hold the handset in the cradle and cause it to depress the hookswitch when
the phone is not in use.
2.8 CONNECTING A HEADSET TO THE IP250D
Two types of headsets may be connected to the IP250D:
a) The type that replaces the handset and connects to the RJ-10 handset cord receptacle
b) The type that connects to a 2.5 mm diameter jack (located on the right front side
of the keyset)
When using the 2.5 mm type, the handset should be left in the cradle, such that it
depresses the hookswitch. Please follow the headset manufacturer’s instructions when
using the type that replaces the handset.
Note: The handset, headset and speakerphone devices have special rules that describe their
modes of use, as described in section 4.7.
Teledex IP250D User’s Guide SIP/MGCP Part Number 600-0480-605
CONFIGURING THE IP250D
3 Configuring the IP250D
Once the IP250D has been unpacked, set up on the desk (or mounted to a wall), and
connected to the network, the network administrator should be notified that the unit is
ready for network configuration and activation. Once the unit has been configured and
activated, it will receive power from the network and begin to function.
Note: The IP250D will not function until it has been configured and activated by the
network administrator.
The user cannot make any changes to the network configuration of the IP250D, but can
make certain changes to suit personal preferences, such as volume settings, ringer tones,
speed-dial phone numbers and the like. These steps are covered later in this manual.
This section contains information on how to access the device’s built in web pages for
further configuration. In order to access the built-in configuration web pages of the
device, you need to know its IP address. If you do not know the IP address of the unit,
refer to Appendix A for instructions on how to determine the unit’s IP address. If the IP
address is known, a web browser URL can be pointed to the address. Doing so will
display the device’s main configuration web page, which will look similar to that shown
below in Figure 3-1. The main configuration menu appears on the left of the screen. The
contents of this menu will differ depending on the purpose of the device, the VoIP protocol which is running on the device (if any), and whether the device is executing the main
application or the downloader application.
Note the following web browser requirements:
• Javacript must be enabled.
• For optimum viewing of the device's web configuration pages, we suggest
configuring your system display to a minimum viewing resolution of 800x600
and your browser display maximized to fill the viewing area.
• To avoid potential javascript execution errors, we also recommend using
Internet Explorer 4.0 or higher, or Netscape 4.0 or higher.
3.1 THE HOME PAGE
The home page is the first page displayed when the device’s web pages are accessed. It
shows how long the device has been running since its last reboot, the IP address the
device is currently using, whether or not the device is password protected, and also displays the main application and downloader application firmware versions. To navigate
the system settings, click on the selections to the left side of the page.

3.2 LAN CONFIGURATION
The LAN Configuration page allows configuration of the device’s local network settings.
Sub-pages are available to configure the LAN Interface settings.
3.2.1 LAN Interface Settings
This sub-page allows the user to configure the device’s LAN interface settings. Select
whether you wish for the device to be configured via a DHCP server on the network, or
statically configured. If you wish to statically assign the network settings, enter the IP
address, subnet mask, default gateway IP address and DNS server IP address. It is also
recommended that the network domain name be provided as well, to ensure correct DNS
operation. Press SAVE LAN SETTINGS to save the network settings.
3.2.2 VLAN Settings
To enable VLAN for network traffic, set the VLAN TAG AND PRIORITY TAG. Press SAVE
VLAN Settings to save the VLAN settings. Reset the unit to have the new settings take
effect.
3.3 MGCP CONFIGURATION
If the device is running the MGCP protocol, select MGCP from the menu. This will
provide sub-options to configure the MGCP server and device endpoint settings, how the
device is to handle any out-of-band (OOB) DTMF signaling, and VLAN prioritization
for MGCP packets.
