Sun Aug 25 11:14:01 MSD 2013

hi jayanath
i am attaching the error as well as the console log which i see when i load
mod_gsmopen in freeswitch.
i typed the commands:
console loglevel 9
fsctl loglevel 9
load mod_gsmopen

after which the log that i received is attached in log file and the error
which was in red is attached in error file respectively.

thanks
Ashish Mishra
