Thanks BP,
At the end of the day I know it's pretty simple stuff, and the RTF procedures give a framework to communicate. The actual situation dictating what you might say.
It just seems that something ( an inital call) that may be considered a basic and fundamental apsect of RTF seems to have a few variations documented in CAP413.
Probably like a few others RTF is my weakest area, so I need to adopt the correct proceudre so that it becomes second nature and then there is one less thing to worry about.
Thanks for the help.
