Without detailed documentation to do what I want, it makes trying to get 
this to work a little more... adventurous. Callweaver is a fork of 
Asterisk 1.2, with a lot of SIP and Fax centric solutions they tied it 
(all in all pretty stable and decent) so changing between the two should 
in theory be simple. I was hacking around in the voiceglue perl files 
(the main part I couldn't get to work out of the box, I may be looking 
at the wrong spot though) and replaced all AGI statements with OGI 
statements, to match callweaver, and replaced all asterisk mentions with 
callweaver (configuration file as well) but voiceglue.pl dies with tons 
of errors relating to 'unknown configuration option' which is where I am 
stumped, I don't quite get where the config syntaxing is happening in 
VoiceGlue. That and the log doesn't quite work with the perl file (it 
works perfectly with everything else, go figure on that) and all the 
other subsystems for the platform so far work, but without a tie in, I 
can't test beyond the aspect of 'yup, it runs'

My output is:

Cannot write to log file: Bad file descriptor at voiceglue line 633

/etc/callweaver/callweaver.conf : Cannot ...', 'VOICEGLU', 'eiji.tsu')

The callweaver config file is set up like this:

[general]
cwrunuser => callweaver
cwrungroup => callweaver

[directories]
cwetcdir => /etc/callweaver
cwmoddir => /lib/callweaver/modules
cwvarlibdir => /var/lib/callweaver
cwdbdir => /var/lib/callweaver
cwogidir => /share/callweaver/ogi
cwspooldir => /var/spool/callweaver
cwrundir => /var/run/callweaver
cwlogdir => /var/log/callweaver
cwsoundsdir => /share/callweaver/sounds
cwkeydir => /share/callweaver/keys

[options]
systemname => callweaver
enablespaghetticode => no

[files]
cwctlpermissions = 0660
cwctlowner = apache
cwctlgroup = apache


it might be something simple, but I am not catching it so far.  I can 
provide as much support with my side of the testing as possible, and 
work on the perl code a bit (I am only moderately versed in perl, and 
that is on the side closer to novice, so I can hack, but I tend not to 
be so hot at really complex items, at least yet)
