[Freeswitch-users] mod_gsmopen: some success - hear crackly unintelligible announcement

Sun Aug 25 11:43:11 MSD 2013

In future pls use pastebin to upload logs, instead of attaching them to
emails! These days people check mails on tablets etc., so large attachments
become a problem for them :-) !  Also, might be better to run this in an
independent thread and not use the existing threads.

I see this:

What does: "ls -l /dev/ttyUSB*" tell you ?
I presume that you are running FreeSwitch as a root, or as a user that has
been added to sudoers or similar logic to achieve root privileges at run
time ?
Also, did you try "wvdialconf /etc/wvdial.conf" as root ? It'll tell you
which ports are modem ports (i.e. control ports... as against voice ports
-- USB bulk transfer) ?
