Thanks for the link, I saw that before. It mentions:

Is there any guidance on how to achieve any of he above to deploy the iCall?

Never done this before but i think you have to import the script over tmsh

create sys icall script 

To create a script while at the tmsh prompt...

1. type: edit sys icall script
