[Freeswitch-users] Help understand error message -- gsmopen fails

Looks like, not many people use mod_gsmopen. I've opened a JIRA ticket for
some minor issues in the Wiki, but hasn't been acknowledged, and I see no
one responding this mail either. I'd seen your other mails in the archive
while searching for hints in previous exchanges.

Ubuntu/Debian setups should be fairly similar. Did you follow the wiki to
build it from scratch or using the repo packages ? I guess the former,
because Debian repo packages didn't have mod_gsmopen.

I plan to spend a day or two reading about FS. The wiki has a tonne of info
but not in a very well organized fashion. Also, I saw that the JIRA bug
reports have lot of useful information in them.

BTW what are you trying to do with FS ? Set up an IVR ?
