Using Fax Voip with AXON PBX

1.      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.

Comments about using FaxVoip with AXON PBX

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.
