CentOS - Apr 2013 - Asterisk, IAXModem and Hylafax

Arch = x86_64
OS = CentOS-6.3 (FreePBX)
Asterisk = 11.3.0 (FreePBX)
Hylafax+ = 5.5.3  (epel)

I am installing an Asterisk server with the intent of having it act as
our fax server.  The Asterisk system was installed using the current
FreePBX distro which is reputedly based on CentOS-6.3. I have
installed Hylafax+ from epel and I have built and packaged
IAXModem-1.2.0 for CentOS-6 using mock and installed that on the
Asterisk host.

I am past the point of setting up Asterisk and configuring extensions
and users.  I am able to place and receive internal calls to and from
SIP devices and place and receive external calls over a PSTN analogue
trunk.  The echo generated by the SIP clients is terrible but that
problem can wait until I get to dealing with voice service
implementation.

At the moment I am trying to get Hylafax configured.  I have done this
in the past albeit for systems using external serial modems.  I am at
the point of running the faxstup utility which builds the necessary
hylafax configuration files.  I am getting these errors from the
utility:


Setting Ghostscript font path in /etc/hylafax/hyla.conf.


Warning: /usr/local/lib/ghostscript/fonts does not exist or is not a

This is the directory where the HylaFAX client applications expect to
locate font metric information to use in formatting ASCII text for

illegible facsimile from ASCII text.

These packages are installed:
Installed Packages
ghostscript.x86_64      8.70-14.el6_3.1
@anaconda-CentOS-201207061011.x86_64/6.3
ghostscript-fonts.noarch
                        5.50-23.1.el6  
@anaconda-CentOS-201207061011.x86_64/6.3

Can anyone tell me what package I am missing or what else might be
causing the problem?  I realize that this is only tangentially a
CentOS question so I crave the list's forbearance.

I've run into this quite often. Typically I just create a symlink to where
the font data is, then rerun 'faxsetup'. Ex:

ln -s /usr/share/ghostscript/8.70/lib /usr/share/ghostscript/fonts

Then, all is well.

Also, unrelated, ensure you disabled tokens in your Asterisk IAX config.
Otherwise, iaxmodem will not register as it does not support tokens at this
time.

Thank you.  After I wrote I checked in /etc/hylafax/hyla.conf and that
listed some of the directories where fonts are found in CentOS-6.3 and
many places where they are not. So I treated the error message from
faxsetup as spurious and proceeded on that basis.  I had already
encountered the difficulty with tokens and had set that to 'no' in the
fax device profiles.  (We are using the users and devices mode of
Asterisk rather than extensions.)

I can now register each of the two fax lines I have configured. Albeit
one at a time because I have only one spare POTS line to play with.
However, whenever I call in I only get the ss-noservice.ulaw
recording.  I assume that is specifically an asterisk question so I
will take to the Asterisk users list.

Thank you again for your help.
