Configuring QX IP PBXs with Flowroute
Revision 1.0 4 26-Sep-16
1 Introduction
This document describes how to configure the Epygi QX IP PBXs (herein IP PBXs) to use the VoIP SIP trunking
service from Flowroute. The IP PBX is capable of making IP-PSTN calls via Flowroute SIP trunks. This solution
allows IP PBX users to make cost saving calls to the global PSTN.
Please Note:
•The described configuration is generic for all Epygi QX IP PBX models, such as the
QX50/QX200/QX2000/QXISDN4+.
•Security issues and calling rates are beyond the scope of this document. See the listed documents in
References section to get more information on the security related issues.
2 Scenario
Provider: Flowroute SIP Trunks
•offers outbound and inbound calls
•allows parallel outbound calls to be made from one account
•allows parallel calls to be received on one account
Customer:
•The customer will be making long distance cost saving PSTN calls through the Flowroute SIP trunks.
2.1 Requirements and Preparations
•The IP PBX is connected to the network and all network settings are properly configured.
•The IP PBX is running software version 6.1.x or higher.
2.2 Account Information from Flowroute
Flowroute will provide the customer with the following data (all data used below are just samples):
•Username – 49135259
•Password – ************
•SIP Registrar – sip.flowroute.com
•Signaling port for SIP Registrar – 5060
•Telephone number(s) (DIDs allocated to the customer) – 12012994794, 12015354360

3 Configuration
The Flowroute allows both IP-based authentication and SIP registration when configuring VoIP PBX systems.
The QX VoIP Carrier Wizard supports both methods; however, the SIP registration is used in the configuration
below.
The two sections below describe the configurations required on the IP PBX to allow the users to
•Make outgoing calls through the Flowroute SIP trunks.
•Receive incoming calls from the Flowroute SIP trunks.
3.1 Making Outgoing Calls through Flowroute
To create a new extension on the IP PBX and configure it with the provided account automatically follow the
steps below:
1. Go to the TelephonyVoIP Carrier Wizard page, pass through the wizard by inserting the below listed
parameters:
Select Manual for VoIP Carrier
Description – optional
Press Next (Figure 1).
Figure 1: VoIP Carrier Wizard – page 1
2. Insert the following parameters in the next opened page:
Account Name – the Authentication Username provided by the Flowroute (e.g. 49135259)
Password – ************
SIP Registrar – sip.flowroute.com
SIP Server Port – 5060
Enable Use RTP Proxy service and press Next (Figure 2).

Figure 2: VoIP Carrier Wizard – page 2
3. On the third page of the VoIP Carrier Wizard define the Access Code (e.g. 1) which will be used in the
IP PBX Call Routing Table for making outgoing calls through the Flowroute, and the IP PBX extension
which will receive all incoming calls from the Flowroute SIP trunks (e.g. extension 00; it is the IP PBX's
default Auto Attendant). Routing all incoming calls to the Auto Attendant is the most frequently used
scenario. Defining another extension as the call receiver is also applicable.
Access Code – 1
Emergency Code – leave the default value or put your country emergency call
Route Incoming Calls to – 00.
4. Enable the Failover to PSTN service if it is desirable to allow calls failover through IP PBXs onboard FXO
lines or trunks ( N/A on the QX2000) and press Next (Figure 3).

5. Confirm entered settings on the last page of VoIP Carrier Wizard page and press Finish (Figure 4).
Figure 4: VoIP Carrier Wizard – Summary page
Now the provided account is configured on the automatically created extension 999. This allows making
outgoing calls through the Flowroute SIP trunks using the settings for extension 999 (Figure 5). The appropriate
Call Routing rule with 1* pattern is also automatically added on the Call Routing table (Figure 6).

Figure 5: Extensions Management page
Figure 6: Call Routing Table page
How this rule works: The IP PBX will route all outbound calls matching the prefix 1* through the Flowroute SIP
trunks.

1.1 Modifying Caller ID for Outbound Calls
The Flowroute allows the outbound Caller ID to be modified. In the outgoing SIP Invite message Flowroute
needs to see a known number in the P-Preferred field using the globalized E.164 format (+1 and 10 digits) in
order for outbound calls to be allowed, recognized and called back. Epygi does support this and it is doable in
the call routing entry for outgoing calls as follows:
1. Go to TelephonyCall Routing page, select the outgoing Call Routing entry *1 and press the Edit
button. The Call Routing Wizard appears.
Enable the Filter on Source/Modify Caller ID option and press Next.
Figure 7: Call Routing Wizard page
2. On the second page deselect the Use Extension Setting field, fill-in the Username and Password fields
with information from Flowroute and press Next (Figure 8).

3. On the next page, enter the following parameters:
Source Number Pattern – *
Source Type – PBX
Number of Discarded Symbols – 99;
Prefix – 12012994794 (new Caller ID number)

4. Press Next and finish the wizard.
How this rule works: Outgoing calls will now have the new Caller ID as the DID 12012994794.

3.2 Receiving Inbound Calls from Flowroute
Apply the provided DID number in the SIP Settings for the auto attendant extension 00, in the SIP Settings-
Username/DID number section, and save (Figure 10).
Figure 10: Extension 00 – SIP Settings page
How this configuration works: The system will route all inbound calls from the Flowroute SIP trunks matching
the pattern 12015354360 to the auto attendant 00 on IP PBX.

4 Additional Notes
4.1 Sending Music on Hold to Remote Parties
Each extension of the IP PBX can be configured to send its own hold music to remote parties on hold (PSTN,
IP, or IP-PSTN destinations). While sending the extensions’ music on hold (MOH) to PSTN parties does not
require any configuration on the IP PBX, certain configuration is needed when the remote party is an IP or IP-
PSTN destination. The following steps describe how to configure an extension to send its own MOH to remote
IP parties:
1. Open the Basic ServicesHold Music Settings page (Figure 11).
2. Enable the Send Hold Music to remote IP party checkbox and press Save.
Figure 11: Basic Services – Hold Music Settings page
If the IP PBX is configured with an ITSP that does not support remote MOH (the ITSP closes the received
audio stream when receiving a SIP re-INVITE message with the c=IN IP4 0.0.0.0, a=send only media
attributes), please follow these steps to complete the configuration:
1. Go to the "http://xxx.xxx.xxx.xxx/generalconfig.cgi" hidden page (Figure 12).
2. On this page, select the Force Hold Music checkbox and press Save.

4.2 Sending and Receiving Faxes through the Flowroute
To send a FAX connect the FAX machine to one of FXS ports on IP PBX and enable T.38 FAX and Enable Pass
Through FAX options in the codecs’ list for the corresponding FXS extension (extension 102, FXS-2 in this
example).
For receiving FAX from the Flowroute SIP trunks you can use an already created configuration through the
VoIP Carrier Wizard. After the additional configuration steps described below you will receive FAX on the FAX
machine attached to the FXS-2, extension 102:
1. Choose the ExtensionsExtensions Management page.
2. On the Extensions Management page, click on the Codecs link of the extension 102.
3. On the Extension Codecs page select the Enable T.38 FAX and Enable Pass Through FAX checkboxes
(Figure 13).

Revision 1.0 15 26-Sep-16
Figure 13: Codecs page for extension 102
These are the configuration options for receiving FAX on the IP PBX:
•Incoming calls are routed directly to the extension with the FAX machine attached. A special DID
number is dedicated for that extension in this case.
•Incoming calls are routed to the Auto Attendant with FAX forwarding enabled to the appropriate
extension. Pressing START from the sending fax machine while listening to the Auto Attendant
greeting message will forward the call to the predefined FAX extension that has the fax machine
attached.
The QX IP PBX also allows receiving FAX messages as a TIFF file into the extension’s voice mailbox if there is
no FAX machine attached to the extension. In this case the following should be configured on that extension:
•The voice mail service should be enabled (default).
•Enough memory space should be allocated to the selected extension for storing incoming faxes.

Revision 1.0 16 26-Sep-16
•The No answer timeout should be set to its min value in the extension settings.
•The Enable T.38 FAX and Enable Pass Through FAX options for that extension should be enabled
as well.
Please Note: In all scenarios the Enable T.38 FAX and Enable Pass Through FAX checkboxes should be
selected for the FAX extension.
