教程 - Fax in and out with Asterisk (實現VOIP網絡傳真)

本帖最後由 ckleea 於 2011-4-5 09:09 編輯

將過去一些心得分享，希望大家能使用現有VOIP設備去達成各樣通訊目的。

基本設備
1. working asterisk and linux server
2. working apache web service on your server


ISTP 網絡供應商要求
1. not all ISTP allow fax. Please check your provider
2. some include free fax for limited pages e.g. HKBN 2b
3. the best would be a PSTN line connected to your asterisk

Fax server/client software
1. hylafax server  http://www.hylafax.org
如果用 rpm經 yum install 裝就最簡單；亦都可以考慮用srpm 裝，不過會出現兩個files - server and client，兩個都要裝

2. free fax for asterisk from digium http://store.digium.com/productview.php?product_code=804-00007
需要在digium 開account，購物，不過唔使俾錢
只有一條channel

3. iaxmodem
http://iaxmodem.sourceforge.net/
經它裝 asterisk and hylafax 連上

4. avantfax http://www.avantfax.com/
GUI frontend to send and receive fax everywhere

5. other
windows fax printer to send fax from Windows based PC
http://www.hylafax.org/content/Related_Software

Asterisk configuration

Web based fax client
1. www.outfax.com 免費，可註冊
2. http://www.tpc.int/sendfax.html 完全免費


Other
Incoming fax via ATA - not tested

Faxing using Asterisk-IAXmodem-HylaFax

Robust and reliable faxing can be achieved by using HylaFax. Iaxmodem is used to interface Asterisk with HylaFax.

PSTN <-> Sangoma Card <-> Zaptel <-> Asterisk <-> IAXmodem  

IAXmodem website: http://iaxmodem.sourceforge.net/
Softwitch (Spandsp) website: http://www.soft-switch.org/
HylaFax website: http://www.hylafax.org/

Please note that this is a quickstart guide, for more detailed configuration check the respective product websites and READMEs.

1. Package requirements

    libtiff
    libtiff-devel

2. Installing IAXmodem
    Untar your IAXmodem tarball (/usr/src/)
    #> cd /usr/src/
    #> tar xvfz iaxmodem-0.1.14.tar.gz
    Install libiax2:

    The libiax2 source is included with IAXmodem
    #> cd /usr/src/iaxmodem-0.1.14/lib/libiax2
    #> ./configure
    #> make; make  install

    Install spandsp:

    The spandsp source is included with IAXmodem
    #> cd /usr/src/iaxmodem-0.1.14/lib/spandsp
    #> ./configure
    #> make; make  install

    Install IAXmodem and create a symbolic link for IAXmodem in /usr/sbin

    #> cd /usr/src/iaxmodem-0.1.14/
    #> ./build
    #> ln -s /usr/sbin/iaxmodem iaxmodem

3. Running IAXmodem

    IAXmodem can be run in daemon and non-daemon mode, it is recommended to run IAXmodem in non-daemon mode during the installation/configuration for easier debugging and then run it in daemon mode once all configuration is working.

    Create the /etc/iaxmodem/ directory to store your  IAXmodem configuration files:
    #> mkdir /etc/iaxmodem

    You will need a separate configuration file for each fax line. Configuration for each fax line are  stored in /etc/iaxmodem/<name of fax device>.

    Create a configuration file for a fax device called ttyIAX1
    #> vi /etc/iaxmodem/ttyIAX1
    ---begin here---
    device          /dev/ttyIAX1
    uucp:uucp
    mode            660
    port            4571 ; you will need a different port for each device
    refresh         60
    server          127.0.0.1
    peername        iaxmodem1
    secret          password
    cidname         John Doe
    cidnumber       8005551212
    codec           ulaw
    ---end here---

    For more details about parameter options, see /usr/src/iaxmodem/README

    Add an IAX account for this modem in Asterisk:
    #> vi /etc/asterisk/iax.conf
    ---begin here---
    [iaxmodem1]
    type=friend
    secret=password
    host=dynamic
    port=4671
    context=outgoingfax
    allow=all
    ---end here---

    type "reload" in the Asterisk CLI to apply changes.

    Start IAXmodem for ttyIAX1
    #> iaxmodem ttyIAX1

    Start hylafax for ttyIAX1

For IP01 users who have installed switchfin firmware, you may refer to this page for information of fax over IP01.

http://switchfin.org/index.php?o ... Ablog&Itemid=53

I have not tested this.
  1. Attrafax fully tested
  2. Saturday, 18 September 2010 00:00

  4. Hi Guys,

  6. During last month we have fixed some bugs related with the Fixed point implementation of Attrafax in Switchfin.
  7. Switchfin and the Fixed point Attrafax now passes all FAX tests as defined below:


  10. In order to formalize the tests let's follow the original notation of attrafax-0.9/doc/t38-tests
  11. with some Switchfin interpretation.


  14. So let define our setup like this



  18. fax <-> dahdi <-> IP02/IP08 <-> sip <-> Zoiper


  21. user 6000 -> DAHDI/1 and fax connected to it, this is reffered to PSTN below
  22. user 6001 -> sip account for Zoiper soft phone

  24. Required configuration:


  27. /etc/asterisk/chan_dahdi.conf

  29. faxdetect = both

  31. sip.conf - In both the global section and the device sections for the
  32. t38-capable devices add

  34. t38pt_udptl = yes
  35. Dialplan:


  38. fax = 6000
  39. zoiper = 6001

  41. [default]
  42. ; tdm part =======================
  43. ; fax gw
  44. exten => ${fax},1,Dial(DAHDI/1)

  46. ; standalone app
  47. exten => 6701,1,RxFax_T30(/tmp/t30rx,6701)

  49. ; sip part ========================
  50. ; fax gw
  51. exten => {zoiper},1,Dial({zoiper})

  53. ; standalone app
  54. exten => 6702,1,RxFax_T38(/tmp/t38rx,6702)

  56. Tests:



  60. 1) Testing the gateway. The test is done in both directions.

  62. SIP-receiving, PSTN-transmitting gateway

  64.             test G01: Send one page from fax to zoiper (extension 6001) and see if it's received ok.
  65.             test G02: Send 10 pages from fax to zoiper (extension 6001) and see if it's received ok.

  67.     PSTN-receiving, SIP-transmitting gateway

  69.             test G11: Send one page from zoiper to fax (extension 6000) and see if it's received ok.
  70.             test G12: Send 10 pages from zoiper to fax (extension 6000) and see if it's received ok.

  72. 2) Testing the T30 (PSTN) applications:

  74. Receiving a fax from the PSTN

  76.             test G21: Send one page from fax to file (extensions 6701), see the received file.
  77.             test G22: Send 10 pages from fax to file (extensions 6701), see the received files.

  79. Sending a fax to the PSTN:

  81.             test G23: sending a tiff file to the fax. We do this test using call file like this

  83. Channel: DAHDI/1
  84. MaxRetries: 0
  85. RetryTime: 10
  86. WaitTime: 30
  87. Application: TXFAX_T30
  88. Data: /tmp/onepage.tiff|123456


  91. 3) Testing the T38 (SIP) applications:


  94. Receiving a fax from Zoiper

  96.             test G31: Send one page from Zoiper to extensions 6702, see the received file.
  97.             test G32: Send 10 pages from Zoiper to extensions 6702, see the received files.


  100. Sending over SIP, normal apps:

  102.             Test G35: sending a tiff file to Zoiper. We do this test using call file like this

  104. Channel: SIP/6001
  105. MaxRetries: 0
  106. RetryTime: 10
  107. WaitTime: 30
  108. Application: TXFAX_T38
  109. Data: /tmp/onepage.tiff|123456


  112. Source Code:

  114. To enable Attrafax in Switchfin just enable it in menuconfig.

  116. For people willing to use it on other platforms fixed point Attrafax patch can be found in our SVN at
  117. https://switchfin.svn.sourceforge.net/svnroot/switchfin/switchfin/trunk/package/attrafax/attrafax.patch
  118. The Patch should be applied against Atrafax-0.9.

  120. We are using Asterisk 1.4.32 and to get the Attrafax gateway functionality working you need to apply the patch at
  121. https://switchfin.svn.sourceforge.net/svnroot/switchfin/switchfin/trunk/package/asterisk/asterisk-attrafax.patch

  123. On the fixed point Blackfin CPU we got about 700% speed up. Speed up on a systems with floating point support (like x86) will not be that much but probably still significant.
  124. Let us know if you get some performance measurements on x86 or other platforms.


  127. Once again thank you Zoiper guys for sharing Attrafax!
