CESID number

[caknfd]

We have a new install with 14 sites. Each site has a local trunk for 911 notification. All phones will be homed to a controller at the main site with a PRI (most will failover back to a local controller at the local site) instead of routing 911 calls back through the local controllers could I just put the local number at each site as the CESID number in the main site for all of the phones at that site and route all 911 calls out the PRI. In a failover mode the users will be on the local controller to use the line directly (not all sites will have a local controller and may use LIM's)

On the system side - Yes, when 911 is dialed, the Caller ID defined in the CESID value will be presented to the 911 answering point.

You will need to have your PRI service provider work with the 911 center to make sure the database has the correct physical address associated with the number you present in CESID. They might charge a monthly service fee for this.

If you decide to go this route, TEST after the setup with the 911 dispatch center. We have had cases where it wasn't set up correctly and a real call to 911 is not the time to discover this.

At sites where we have implemented this, it works well. We have had a few times where the wrong info was presented which was discovered in the testing. ~ Mike

The good thing is this new install is for a city and one of the sites is the Police Department and they are their own PSAP. One thing i'm worried about is will the PRI pass the CESID number. On the PRI in our office I can't CPN a number that does not belong to our PRI carrier. I know CPN is a little different but CESID but who knows.
Since all of the sites have their own local trunk if the address is wrong we can get that corrected. I have just not used the CESID like this. The other advantace is we can use the local notification to a display set to display the CESID Comments to ID a more detailed location of the call besides name and Ext.

Have any of you ever put an ONS/Class extension in the Emergency Hunt Group? The PD Distpatch won't have IP Phones but ONS stations from an ASUII wired into the VESTA console that does the 911 and Business line answering for the PD (the console can display caller ID from the ONS ports) and wonder how the display of the local notification displayed on ONS phones. (Name Ext. # and the CESID Comments field)

Thanks

A lot of Telcos lock down the permissible CPN when PBX controlled. Quite a few more do not allow PBX control at all.

In the event that your Telco will allow foreign numbers to be sent, you should be ok

I've seen the Local Number Routing route based on IP of the phone which would be the best solution but I have yet to experiment with this myself.

Have you researched Location Based Numbers (LBN) and Network Zones. If you specify 911 (and 9911 if you 9 is your digit for outside calling) as an LBN, then the primary controller can assign the CESID to the call AND route that call over the PRI or to the local controller via a Route List. Not sure how this would affect your plan to use LIM for sites without a local controller.

Network Zones

Site 1 (devices + ICP) = Zone 10

LBN prefix 1000
CESID 111-555-1111​

Site 2 (devices + ICP) = Zone 20

LBN prefix 2000
CESID 222-555-2222​

ARS Digits Dialed

1000+911 --> Route List 11

Route List 11

1st choice PRI (strip 7, insert 911, emergency)
2nd choice IP trunk to Site 1 ICP (strip 7, insert 911)​

2000+911 --> Route List 22

Route List 22

1st choice PRI (strip 7, insert 911, emergency)
2nd choice IP trunk to Site 2 ICP (strip 7, insert 911)​

Repeat as nesssecary for the other sites with a resilient ICP, and for 9 911 (assuming 9 is your outside access digit)

The Local Number Routing to IP association that I believe KWB is referring to is configured in the Location Specification form.

Specify the range of IP's (x.x.x.1 - x.x.x.254 for a /24 subnet)
Specify the zone number
Name the zone (not actually a system generated value like the help document indicates, best to duplicate the name from the Network Zones form)

Ensure that the device is set to Auto for zone assignment (Station Attributes form)

Thanks bribob for the assist.

That is exactly what I was referring to.

Works miracles and doesn't require complicated ARS/COR restrictions

Thanks guys, I'm familiar with the location based routing and have used it before. What I'm trying to do is get more information to the PD (will be one of the mitels in our new install) when 911 is dialed without resorting to ER Advisor. Then I found out that the local emergency call notification can also display the comments field from the CESID form. But to enter a comment you have to add a CESID number. That's where I wondered if I could put the number of a local trunk from the remote site in the local site CESID form.(all phones hosted at the local site)So when the remote phone dials 911 it will display the correct number weather I route it out the local PRI (CESID form will send the correct number to psap) or I route the call back to the remote site and out the local trunk. But I get the added benefit of displaying the CESIS comment to give them a more detailed location.
Never used the CESID form before and wonder if there is any drawbacks.

You will not be able to send additional info to the 911 dispatchers without having access to the ALI database - HIGHLY UNLIKELY!

Your goal of sending the equivalent number of an actual number at site will work sometimes and not others depending on what your telco allows.

Using Location Based dialing will force the call to route out the ACTUAL line on site which will always be allowed.

Using Location Based Dialing will remove the Human factor of needing to manually program the CESID database to deliver the correct number - lives are potentially at risk if this is not done.

Using Location Based dialing can be configured by IP range and thus automatically configure all phones at a specific site to dial appropriately without further requirements.

I think you need to re-assess your priorities and liabilities before committing too much further down the path you are on.

Again I'm filimar with the Location Based Routing. Let me clarify what I meant by getting the 911 dispatchers more info (I know it won't send the the info via the ALI database) I planned on a IP phone in the Dispatch area and using the Emergency call local notification to give them more information besides the name and extension (The Local Notification will if configued in the CESID form give you a button labeled location as well as delete alarm and if pressed before delete alarm will display the CESID Comments) So Weather the Telco will pass the CESID Number if I route the call out the PRI or not that is something I have never done and wasn't sure if it would work. I most likey will route the 911 call back to the remote site and still use the CESID Comment for the Local Notification only to give them a better location of the call. Will be most helpful at the Main Sites 2 story building with 100+ phones sending a little more detail about the location of the 911 call.

The other thing I asked about is ONS/Class port can be used as one of the extensions recieving the local notification. We may try and connect an ONS port to the PD's 911 console (as a trunk) and when a 911 call is placed that key will ring and using caller ID Display the Local Notification. Maybe a bit confusing to have a second call ring the 911 console but we can dedicate a trunk on the console and maybe make it flash only so they can check it if needed. Just have never used a ONS port for the Local Noitification.

This is all for a City with 14 Sites City Hall, PD, 5 Fire station etc. and all phones will be hosted either at the PD or City Hall 3300 and this is only for notification to PD for a 911 call from one of the city sites.

I can't comment on the 2nd portion (ONS integration), but here's a questions to figure out if the 1st part is possible. (Sending CESID of analog line at site X out PRI at HQ)

Is the PRI provider at HQ the same as the analog line provider for the remote sites? Assuming yes, then you should insist that they be able to allow the analog CESID be sent out over the PRI.

If it is not the same provider, get the two providers talking and find out if there is an authorization document that you (or the PD) can agree to which will allow CESID from analog provider to be sent on PRI providers network. For my PRI sites, I had to acknowledge that toll fraud is possible and that my company assumes all risks associated with sending (or not sending) a caller ID.

The more Maverick approach, program CESID and ARS the way you want it and make some calls!
Most of the time technicians don't know who to call when they want to warn 911 dispatch of an incoming test call, but you probably know a few people that you could ask. You can always statically assign the CESID to a phone, dial 911 and capture (CCS TRACE) the digits that are sent over the PRI. Assuming the test doesn't go as planned, you've got a pretty good cover story for making non-emergency calls to 911.

Ok, I did not understand that it was your intent to try and deliver emergency notification info via internal phones to the PD. Emergency notification is only delivered to the local system that dialed the call. This explains why you want to route all calls out of a single system (I think). The phone at PD must be hosted off of the same system that will be dialing the call.

I really don't want to be a stick in the mud but I really see so many ways this can fail or cause confusion that were you my customer, I would be strongly advocating against it.

It still comes down to whether your telco will allow the number to be sent. I think you need to cross this off your check list before investigating anything beyond that.

As for your thoughts on the ONS solution. I do not believe the caller ID protocol for the station is the same as the caller ID for a trunk. I would be doubtful that a trunk would accept caller ID that was formatted for a station.
