[cisco-voip] 91 possibly calling 911?

[Kevin Dunn]

>From a telco standpoint it is ABSOLUTELY possible to do this...
in fact most Teclo's have 91(drop) calls forward Call Information to the
PSAP in case the emergency has disrupted the call. This was very indicative
of old access codes and PBX's

>From Call Manager 5.1 the pots dial peers are matched on each digit, so 91
would not match a destination pattern of 911

So I don't think it is possible.  If we are talkign about PRI connections
andnot FXO ports you might want to check with the serivce provider to see if
they are doing interdigit timeouts on their dial peers.  If they are set too
quickly you sending them 9 1 NPA NXX THGP might be too slow betweenthe 1 and
the NPA and THAT telco setting could register a 911 call.  ( pretty far
fetched though)

one thing we do here is whenever a 91 or 911 is called (outside access code
is 8) then there is a CDR dip that emails us so wecna ceck the erroneously
dialed numbers. I bet you have a user who is dialing incorrectly or a sticky
9 button (hits 9 and it sends 2 9's) then the 99 1 will trigger a 9. dial
peer that will contact the PSAP)

Thanks
