Under the settings section we can find the Templates subsection. It contains different templates for determines flows, depending of course on your needs. And the option to create a new template is present right below settings.

A new template will allow us to name it and going to SMS template. We just need to choose which information we want reflected in our SMS job notification.

NOTE: if Call Secure is active it is necessary to add the "Call Secure" option instead of "Phone", so the chosen line and 3 digits are shown on the ticket.
