Shortcode clarification - 911

[DJRabin]

Customer emailed recently that someone in their office had called 911 and got NOTHING... dead air. Luckily, (no one was hurt, and) I was not involved in this deployment and religiously test 911 on all new installations.

But fixing the issue brought some questions to mind. It appears that the issue was a short code:

The SC in question (I removed this and it fixed the issue)
Shortcode: 9
Action: Secondary Dial Tone
Number: .
Group ID: 1

Other pertinent shortcodes included:
Shortcode: 911
Action: DIal Emergency
Number: 911
Group ID: 1

Shortcode: [9]1N;
Action: Dial
Number: 1N
Group ID: 5

Shortcode: [9]N;
Action: Dial
Number: N
Group ID: 5

Group 1 contains analog lines and is the preferred route for emergency calls. Group 5 contains 2 T1 lines.

I'm not sure why this would fail or exactly what the Secondary Dialtone shortcode was doing. I'd love to understand all of these "9" shortcodes better so I don;t feel like I'm guessing as to the outcome.

Thanks!

911 shortcode should look like this:
[9]11 911 DialEmergency 1
or if you want them to dial 9 then 911 use this:
[9]911 911 DialEmergency 1

Also, I would put the 9 . secondarydialtone back in the system shortcode if you want to receive secondary dial tone.

Check this carefully!

I have had similar in the UK, where the prefix in the line tab was removeing the leading 9. I'd test this with a trend on teh T1 to ensure that when you dial 911, 911 is presented to line

Put the secondary dial tone back in.

Put both 911 short codes DOZ put in his previous post in, so if they forget the 9 before dialing 911 it still goes out.

Thanks to everyone for the advice. I was hoping someone could shed some light on WHY I should use the secondary dial tone, and how it's different from using the [9] in a shortcode.

Secondary dial tone simply gives the caller a dial tone to listen to.

th [9] . secondary tone group 1 should be group 0 not gorup 1
