IP Phones and IP Lines Configuration for Quadro IP PBXs
1 Introduction
Every Quadro IP PBX (2x, 4x, 16x) provides the possibility to connect IP phones in addition to the
standard FXS phones. The IP phones will be connected via Ethernet to the Quadro LAN port (Figure 1:
IP Phones and Quadro) and serve as additional phones similar to the FXS extensions. This document
describes the configuration steps that are necessary to setup both the Quadro and the IP phones. The
scope of this document does not cover specific brands or even vendors of IP phones, but should give a
general overview and a guideline.
Chapter 2 General Information provides some additional information for an IP phone scenario. It gives
answers to general questions. Chapter 3 Configuring the Quadro and Chapter 4 Configuring the IP
Phones will then describe detailed configuration steps based on this information. The steps shown in
Chapter 3 are illustrated with actual screenshots of a Quadro 4x (running firmware version 3.0.37). 2x
and 4x/16x models are identical concerning the topics covered here. Older or even newer firmware
version might differ slightly in aspect of the GUI.

2 General Information
Before going into detail, some EPYGI terminology will be explained.
2.1 Lines
With lines we refer to the connection to a phone. There are 2 types of lines on the Quadro:
FXS lines – these are the lines to which analog phones can be attached.
The connectors on the backplate for these lines are labeled phone 1, phone 2...
IP lines - these are not real connectors, but they serve the same purpose, they are connecting
an IP phone which is located in the LAN of the Quadro to the Quadro.
All configuration steps regarding lines can be done by following this menu:
Telephony -> Line Settings. On this page there are 2 different sections:
Onboard Line Settings - referring to the FXS lines.
They are identified by the Line number, which is similar to the labelling on the back plate.
For example:
Line 1 <---> phone 1
Line 2 <---> phone 2
IP Line Settings - the IP lines. The IP-lines cannot be identified so easy, as all of the IP-phones
are connected to the LAN. So it means they are identified implicitly by their username/password
Lets say you are editing the IP Line 3 and you are defining the username: snom-3, then the IPphone, which will contact the Quadro with this username, will be assigned to this line.
So to get not confused with we advise to follow some fixed naming scheme.
Without going into detail, line settings are including only physical details of the phone or how it is
connected to the Quadro. Just examples:
FXS line settings: Type of CallerID transmission.
IP line settings: Username/password to connect to the Quadro.
A line itself cannot be called, unless it is connected to an extension.
2.2 Extension
An extension on Quadro IP-PBX is a complex thing, so simply some mixed facts will be listed to clear
the picture step by step.
First of all, extensions are named by 2 digit numbers between 10 and 79.
As a special extension the Auto Attendant has the number 00.
There can be as much extensions as fit in this number space.
Each extension can be seen as a Quadro user. It means the extension user can log into the GUI
with the extension number and a password. (If set)
Each extension can be called locally by its 2-digit number. (Unless the administrator did not
change that in the call routing table.)

IP Phones and IP Lines Configuration for Quadro IP PBXs
It is possible (and needed in most cases) to attach a line to an extension. It can be either an FXS
line or an IP line. Only if a line is attached to an extension you will be able to make a call from
this extension. If no line is attached to an extension, then it is called a Virtual Extension (VE –
see 2.3 Virtual Extension. By default all extensions have lines attached already.
Each extension may have voice mail, with its own greeting messages and individual settings.
Each extension may register at an individual external SIP server (by default all extensions are
registered at sip.epygi.com)
Each extension has the full set of configurable supplementary services, like
ƒ call blocking
ƒ call forwarding
ƒ many extension ringing
ƒ ...
Each extension (except VEs) may have a Remote Extension.
2.3 Virtual Extensions
Actually a Virtual Extension (VE) is just an extension to which no line is attached at the moment.
So you can attach a line and it will become a real extension and vice versa. Here we will just list the
differences to a real extension and the benefit of a VE.
Differences between VEs and real extensions:
A VE cannot have a remote extension. This is done on purpose and has no technical reason.
You cannot dial from a VE, as there is nothing attached to start a call.
You can call to a VE, but nothing is going to 'ring' (until you have supplementary services defined
for this VE, see below).
What can be done with VEs?
Many things, just some will be briefly listed here.
Group calling. Lets say you have a sales department and you want to have a number to call to all
of them at the same time.
You create a virtual extension like 66, and activate Many Extension Ringing, by adding the
numbers you want to include.
Forwarding to frequent used destinations.
Use to register at a ITSP and share this between all extensions
Other functions like hunting, day / night routing.
2.4 Remote Extensions
For every extension, which is not a VE, you can define a Remote Extension (RE).
More precisely this is not a new extension, but an IP-line, which is connecting an IP-phone from the
remote Internet to the extension. This remote line can be used alternately to the line connected to the
Extension 12 has FXS line 2 attached. It means if somebody is calling to 12, then the analog phone,
which is plugged into port “Phone 2”, will start ringing.
7 November 2005
IP Phones and IP Lines Configuration for Quadro IP PBXs
Now the user of extension 12 is activates the RE. Once this RE is setup and the IP-phone from remote
(hotel, home, other office) is registered at the Quadro, calls to the extension 12 will not ring the analog
phone as before, but the remote IP-phone.
Once the remote IP-phone becomes un-registered, the analog phone will be operational again.
2.5 Small Sample Configuration
This sample configuration is just illustrating how lines, extensions, virtual extensions, ip-phones and
remote extensions form the whole picture. Additionally it servers as the configuration example listed
below. The left side of the illustration shows the internal connectivity of the Quadro, whereas the right
side shows the external connections. The box in the middle illustrates the Quadro itself interconnecting
Figure 2 - Configuration example
Below the same setup in a table view:
Line 1
Line 2
IP Line 1
External Server
308746011 none
SIP phone
ip-1 31
308746031 none
933843388 none
Usernames and Passwords:
A lot of different username/password combinations are used within this scenario, so it is easy to get
confused. There is a maximum of 4 pairs within this configuration. Make sure they match in pairs and
remember they are case sensitive.

IP phone <-> IP Line settings
This pair is used by the IP phone in the LAN to register at the Quadro.
IP phone:
The naming convention is different for
different brands of IP-phones.
On Snom phones it is:
Account, Password
IP line settings on the Quadro.
Telephony -> Line settings -> IP line
On the Quadro it is named:
Username, Password
User GUI <-> Quadro extension
This pair is used to log in as an extension to the GUI of the Quadro with a WEB browser.
Using a WEB browser,
asked for:
Username / Extension, Password
User management and extension settings
Extension, Password
SIP server Account <-> Quadro extension
This pair is used to register the Quadro at an external SIP server
Each SIP service has its own terminology.
Typically are:
Account, Username, DID, SIP username…
User management and extension settings
Registration User Name
Registration Password
IP phone as RE <-> Quadro extension
This pair is needed if you want an IP-pone to register as a remote extension

This document focuses on the most common setup; using IP phones as Quadro extensions. In this case
the Quadro acts as a SIP REGISTRAR server for the IP phones.
The setup is therefore a 3-step procedure.
First we configure the IP Line settings on the Quadro, allowing an IP phone to register to this
Then we create an extension on the Quadro and attach the previously configured IP line to this
Then we configure the IP phone itself to register at the IP Line of the Quadro.
Once the IP phone is successfully registered to the Quadro it can utilize the same features as a normal
extension. (e.g., voice mail, call routing, call hold, waiting, transfer, etc.)
An optional step, which is not related to IP Lines: This Quadro extension can finally register to an
external SIP server just like any other extension.

3 Configuring the Quadro
3.1 IP Line Settings
Log in as admin and open Telephony -> Line Settings -> IP Line Settings and click on IP Line 1.
Figure 3 - IP Line settings
Fill the form according to the screenshot.
3.2 Attach This IP Line to an Extension
By default the Quadro comes with a couple of extensions, some of them have attached FXS lines and
some of them (starting from 31) have attached IP Lines.
The Extensions Management page can be found following Users -> User Management and
Extension Settings.
To verify/edit the settings of extension 31, tick the checkbox in the leftmost column of the extension
and click the Edit link at the top of the table. Check the “Attached Line” listbox to make sure it is set to
IP Line 1.
To follow this part of our example also make sure the data for the external SIP server is correct.
See the Figure 4: Extension Management below:

4 Configuring the IP Phones
Now we need to configure the IP Phone so that it can register to the Quadro. Therefore the most of the
following values have to be set to either match the corresponding values set on the Quadro before or
must be set to reflect the Quadro itself (for example the Quadro LAN IP).
The available IP Phones behave very different from vendor to vendor. Some of them must be
configured using the keypad of the phone, others need to download a configuration file, and others may

have a WEB GUI. Details for individual brands can be downloaded from the tech support section of our
In general following options have to be configured on the IP phone.
1. Proxy IP:
This is the IP address of the proxy server. Enter Quadro’s LAN IP address here.
By default this is
2. Proxy Port
This is the SIP proxy server’s port number. (Default: 5060).
3. Registrar IP
This is the IP address of the SIP registrar. Again the Quadro LAN IP (Default:
4. Registrar Port
This is the SIP registrar’s port number. (Default: 5060).
5. User Name
Enter the same user name that has been entered into the IP Lines Setting
pages (here: ip-1).
6. Display Name
This is used in the display name field of the From SIP header field. Some IP
PBX systems use this as caller ID and some may overwrite it with the string
that is set on the PBX system.
7. Password
The password that is used to register. Enter the same password as on the IP
Lines Setting pages (e.g. ip-1).
