Hello list,
i have successfully completed my trails with voice
mail
now my aim is to do the ivr enableing with sems.
iam useing the ser-0.8.12 of stable version and sems
of stable and latest cvs version.
i have compiled my ivr plugin with the python and i
got the binary file ivr.so
so my doubts are
1) does i need to load this binary file into ser.cfg
2)if so how do i need to load the module into the my
ser.cfg
3) the following is my configuration files of ser.cfg
and sems.conf
4) my expectations with the current configurtions is
that when i invite any other user agent it has to
go to the ivr but instead of this it gives the error
as follows
out put while running sems in debug mode
