Axon is a virtual PBX for Windows or Linux
designed to manage calls. Axon is a very easy PBX
with support for fax t38 calls. You can download
it from our site: http://www.t38faxvoip.com/downloads/pbxsetup.exe
or from http://www.nch.com.au/pbx/index.html
.
2.
Example: we have our AXON PBX at 192.168.0.4:5061
and we have our Fax Voip at 192.168.0.2:5070.
And we want to configure Fax Voip as an
extension of AXON PBX with internal number
101. We also have our SIP provider: sip.provider.com
. All calls from Fax Voip starting with
“00” must go to our provider
via AXON PBX, all calls from provider
must go to our Fax Voip via AXON PBX.
The call from Fax Voip to Number “101”
must go to another Fax Voip line via AXON
PBX (test). The picture below illustrates
the basic using of Fax Voip with AXON
PBX.

To install the AXON PBX
1.
Follow the Axon PBX Setup Wizard.
2.
It’s important: if it is the first installation
of AXON PBX do not install “Related
Programs”. Yor need to understand how AXON
PBX works with Fax Voip. You can
install these programs later, if you want to
learn them.

3.
Create 1 or 2 Internal extensions. You do not
know, if you need more extensions. You can create
additional extensions later. Save username as
“Admin” and password “free”, you can
change “user” and “password” later.

1.
Open Axon Web Control in your Internet
Explorer, enter your Username and Password and
Click the “Open Control Panel” button.

2.
Select “Extensions”

3.
Click the “Extension 101” and check/modify
settings for this extension. If you are not able
to select Outbound Dialing Plan “main”, skip
this step for the first time. Click the “Save
Changes” button.

4.
Select the “External Lines”. Click the
“Add New External Line” button.

5.
Enter your SIP Account details here with the
settings you received from your Service Provider.
You can use the “Advanced Line Settings”
button. if you need. Do not forget to set
“Incoming Calls Ring On Extension... 101”:
this feature will be used for incoming calls to Fax
Voip. Click the “Save Changes”
button.

6.
Click the “Add New Outbound Dialing Plan”
Button in “Dialing Plans” window

7.
Enter a name for your New Outbound Dialing Plan (“main”)
and Click the “Save Changes” Button.

8.
Click “Add Dial Rule”. You need to add
Dial Rule to route all external calls (stats with
“00”, for example) to external line “provider”

9.
In “If number starts with” field enter:
00, In “Dial on Line” field
select: provider . Click the “Save
Changes” Button.

10.
Your outbound Dialing Plan “main” must be
like here. Click the “Save Changes”
Button.

11.
Now you must go to “Extensions”
and do some changes. In “Extension 101” select
“Outbound Dialing Plan”: main. Click
the “Save Changes” Button.

12.
In AXON PBX Console click the <Settings>
button.

13.
In Settings window check “Local Sip
Port to listen on” field. Change it, if
need. Click the <OK> button.

14.
In Fax Voip FaxModem Control Panel
you must change SIP-settings according to AXON
PBX settings.

15.
In FaxVoip FaxModem Control Panel
Click <Apply> button, then click <STOP>
button, then click <START> button.
In AXON PBX console you will see a message
about registration.

1.
To do outbound calls from FaxVoip , you
need to set a task for your fax program to dial
number “00XXXXXXXXXX” and send a fax. FaxVoip
works as an extension 101 of AXON PBX and
calls according to dial-plan “main”,
according dial-rule for “00” to “provider”.
2.
Accepting inbound calls from external provider
to FaxVoip: as the call is comming to “Provider”
line in AXON PBX, AXON PBX
redirects the call to Extension 101 (to FaxVoip).
Now (begining from FaxVoip version 2.0.0)
stable SIP registration is supported, so you do
not need to provide static route to FaxVoip to
work with Inbound Calls.
3.
If your fax program have 2 lines you can do a test
call from one line to another using AXON.
Do the test call from one line to number “101”.
The call will be redirected to another FaxVoip
line. If the another fax line is in
“autoanswer” mode, the fax call will be
answered.
4.
If you have problems with t38-faxing using this
construction, you can try to do some steps. If
there are problems with AXON, you can try:
1) to provide external ip-address for your pc 2)
to provide DMZ for PC with Fax Voip. 3) To
install AXON PBX to another PC... The
behaviour of t38-faxing depens on your SIP-provider,
your sip and network environment, model of your
router, and, of course, your sip provider must
have a support for t38 fax protocol.
5.
If you have problems with inbound faxes (no fax
tone, when dialing to Fax Voip from
external SIP Network), using Fax Voip with
AXON PBX, as for inbound fax calls from external
SIP Network to FaxVoip, it is important to check
"Use static IP address and static mapped
ports" option in AXON PBX "Network
Settings" panel and enter "External SIP
port" and "External RTP port starting
from..." values. No need to enter your
"Public IP address" here. You must also
provide DMZ for PC with Fax Voip.
