Hi,
I am trying to understand the 'exec_msg' command as described in Section 4
of SER Admin Guide. I am just trying to echo the user name (1001) of the
caller on the screen. I use the config file given at the end. On receiving
the INVITE message, SER DOES echo the user name, but I also get some warning
and error messages as shown below:
#> /opt/ser-sems/sbin/ser -f /xxx.../voip/ser_expt.cfg

Can someone tell me how I can get rid of these messages. My aim was just to
get the user name displayed, and this has been achieved. I just want to
understand the reason for these warnings and error messages.
Thanks
Frq
