Hello, I am trying to upload a script onto SER using the "serctl fifo UPLOAD_CPL user(a)xxx.xxx.xxx.xxx /path/to/file.xml" command.It is very simple script to reject a call from caller 2093. Unfortunately I have the errors seen below. I have included my simple cpl script, the errors and the relevant part of the ser.cfg. Any help would be greatly appreciated. Many Thanks, Aisling.
