RE: [Asterisk-Users] Asterisk and Fax part 2

[Alexander Lopez]

 Get a regular POTS line and put a 50.00 fax on it.

There are too many variables,

1.  Does your provider really give you a clean g.711 connection or are they 
routing you from a VoIP based Trunk.

2.  The internet may not provide the bandwidth or the relability you need 
to have a fax connection.

3.  Faxing for me works over IP but it is over a point to point network or 
a network that respects my QoS

 Subject: [Asterisk-Users] Asterisk and Fax part 2
 
 Hello,
 
 I've been trying to setup a Fax2Email mecanism on my Asterisk 
 box.  I have been using the following:
 
 1) An incoming IAX line on Unlimitel (Im not even sure if 
 it's worth mentionning the provider, but I do just in case)
 2) NVBackGroundDetect from Newman Telecom
 3) The following extension to test: 
   exten =
 fax,1,SetVar(FAXFILE=/var/spool/asterisk-fax/${UNIQUEID}.tif)
   exten = fax,2,rxfax(${FAXFILE})
 
 4) A fax on a PSTN line to test the fax-to-file part of the system.
 
 Now, the extensions are called when appropriate, and the 
 system seems to work...until the fax actually tries to send 
 the image, and then I get a LINE ERROR on the sending fax.  
 The actual error code goes something like this:
 COM.E-7
 
 In IAX.conf, I have configured it as disallow=all and 
 allow=ulaw as specified in the instructions I found on the 
 following page http://www.voip-info.org/wiki/view/Asterisk+fax .
 
 Where should I start looking to resolve this issue?
 
 Mike

Just a quick note, make sure /var/spool/asterisk-fax/ exists and is
writable by whatever asterisk runs as. Assuming your connection is
good enough, I had LINE ERRORs because app_rxfax aborted right after
the handshake as it would not write the output file. I think there is
a debug mode in app_rxfax that may shed some light. Otherwise see
Alexander's reply about the connection quality.
