Thanks again for taking the time to clear up the coonfussion which is occuring inside my brain! That has helped clarifying things. I am not surprised I got a little lost along the way when I was trying to piece it together myself!
On another note, I thought I had broke my system by tampering with the setting, but it seems like my SIP provider has gone down…talk about coincidence!
Anyway, when it is back up and running I will let you know how I get on.
