1) in ser.cfg iam loading the module tm.so


2) in sems.conf iam usieng ivr path


3) in ser.cfg iam useing like


if(!vm("/tmp/am_fifo","ivr"))


and my ser.cfg

and the output iam getting are as followed

(1254) ERROR: reply (AmRequest.cpp:335):
AmRequestUAS::reply: 500 command 't_reply' not
available

my aim is to run the ivr.py and to get the 
dtmf recorded in to a variable .

when i run the command serctl fifo which
it doesnot shows t_relay porcess in that

so any hints to go from here

your help will be highly appreciated
