It seems there is no quick answer to "#" for security system.
So going back to setup:
Under Phone -> DigitMap (after reply 4) I have
((Mli)|[1-9]x?*(Mpli)|[1-9]S9|[1-9][0-9]S9|911|**0|***|#|**1(Msp1)|**2(Msp2)|**8(Mli)|**9(Mpp)|(Mpli))
Phone -> OutboundCallRoute (after reply4) I have
{(Mli):li},{([1-9]x?*(Mpli)):pp},{(<#:>|911):li},{**0:aa},{***:aa2},{(<**1:>(Msp1)):sp1},{(<**2:>(Msp2)):sp2},{(<**8:>(Mli)):li},{(<**9:>(Mpp)):pp},{(Mpli):pli}
Most of the stuff is due to default (other than as instructed in reply 4)
IMHO azrobert may have overlooked that the default setting here include 911 to be routed through Phone. azrobert suggested that I add xxx in the Line digitmap as I wanted three digit to be routed to analog line. I have verified that a three digit call to 311 gets routed to analog phone. County is not going to be happy with test call to 911
Q: To prevent 911 to go through to Phone, should I make the following changes.
DigitMap change [1-9][0-9]S9|911|**0| to [1-9][0-9]S9|**0| (strip out |911)
OutBoundCallRoute change {(<#:>|911):li} to {(<#:>):li}
I still dont feel very comfortable in making the changes without consulting. Once burnt, twice shy , I guess
