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 directory!

The directory /usr/local/lib/ghostscript/fonts does not exist or this file is not a directory. This is the directory where the HylaFAX client applications expect to locate font metric information to use in formatting ASCII text for submission as facsimile. Without this information HylaFAX may generate 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.

  • 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.
