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

Using the default dialplan. I have only 1 dongle at the moment, so doing a
telephone -> telephone mapping won't work (well, at least, based on what
I've understood so far -- I could be wrong). Tomorrow, I plan to walk
through the dialplan to understand it somewhat better. My eyes don't take
XML too kindly !!

As such no significant changes. The only few hiccups to build, and the
previous segfault I got, I filed a JIRA for, and that has the steps I took
and my preliminary findings.
http://jira.freeswitch.org/browse/FS-5721
http://jira.freeswitch.org/browse/FS-5727

I used a trick I found in the mail archives to use "wvdial" to identify the
control port. After that, set the usb ports for control/audio correctly in
the gsmopen.conf.xml file. After this the module started getting loaded
properly, but I noticed that the signal strength was too low. Post that, I
had to use a long USB extension cable to keep the dongle outside the
window, and ensured that signal strength (RSSI) was good enough. After
this, the rig started working.
