[cisco-voip] Strategies for "Accidental" 911 Calls

[Carter, Bill]

I just converted a customer to a CallManager system with 1200 IP Phones.
Since the upgrade they have had a rash of "accidental" 911 calls.  I
think the old system relied on inter-digit timeout to give users a few
seconds to realize they dialed 911 and they could hang-up before the
call proceeded.  With CallManager, as soon as 9.911 is pressed the call
is sent.  Of course the users need to be trained to remain on the phone
and tell the PSAP they mis-dialed....
 
I am looking for suggestions for what I can do to minimize "accidental"
911 calls.  After 2 weeks on CallManager, the police department paid a
visit and said these "accidental" 911 calls need to stop, or the
customer will be fined.
 
Emergency Responder is deployed so I have 911 and 9.911 defined as
translation patterns.  I had thought about also adding 911# and 9.911#
translation patterns so inter-digit timeout would provide several
seconds of delay.  Any thoughts?
