It would probably make sense to use SAIL if you were already using SME server. In some circumstances, i guess, the SME server would be a gateway machine that’s not doing a vast amount and with enough power to run a small pbx as well.
I don’t know how easy remote administration is with A@H, but i’m assured by a friend who installs and maintains SME server in a few places that SME is good for remote admin.
Never having used either of them, though, i couldn’t say for sure!
Ah, okay, I was unaware of SME Server until now:
Will read up, thanks.
