Changing site setup?

[Plumcrazy09]

Well let me start by trying to explain what I have going on here. Our system was just installed a week ago. The installer setup our system with two sites, Headquarters & Fire Dept. Our headquarters site consists of 4 buildings all connected with fiber. Our fire dept. is two miles away connected with a point to point T1. Well we are having some issues like E911 at our headquarters site currently shows the address for our main building when someone calls 911from any of the other 3 buildings. There are some other minor issues but thats the biggest.

Here's my question... Can my HQ sites be broken up into 4 seperate sites (1 for each building) and if so, will it require a ton of reconfiguring? By having each building be a site I believe I can have the 911 issue solved by using a physical analog line at that site for 911 calls.

Does each building have a different Subnet (IP)? If so, just define your IP Phone address map for each building. That would be the easiest.

If they are all on the same subnet, then the best way to do this would be to create a DHCP reservation for each phone in DHCP, defining which phone is in each building, then do the address map. details here: http://www.shoretelforums.com/forums...ia-script.html

They are on there own subnets. Here's how I'm configured...

Building 1 - 192.168.1.0
VLAN 192.168.0.1
All Shoregear is at building 1 including 2 120/24's & a Shoregear T1. Each building has an Adtran 1224ST POE switch.
Building 2 - 192.168.21.0
Building 3 - 192.168.31.0
Building 4 - 192.168.41.0

Do I need Shoregear at each building?

This is simple.

Go to IP PHONES | IP PHONE ADDRESS MAPS
Click NEW
Select site (several different maps can be assigned to one site, so select HQ)
Put in the low and the high IP addresses (i.e. 192.168.21.1 to 192.168.21.254 for building 2)
Assign a unique Caller ID to this building. Make sure you carrier has the correct CESID Location information for the number you assign. (i.e., make sure the number you assign to building 2 has the address of building 2 associated with it. You might already have a number from when you ported that has this assigned, so use that one).
Call your local PD to test and verify correct address projection.

Done.

10 min's and your done.

Charles -

I'm no installer and I'm not sure what a CESID is or stands for. Maybe I don't need to know. So your saying I can break up my existing site called HQ into seperate sites by building # just by creating new sites and assigning the appropriate subnet to that site? Then assigning the phones to the new site(s)? If I have an analog number at these sites can I or should I use those #'s for the caller ID?

Thanks for the help.

You don't have to create new sites. Just create some IP address Maps.

Example, I have 2 offices in Ft Myers, So i create 2 IP Phone Address Maps:



In the actual settings, I assign the CESID for that site... then I am done. Any IP phone that calls from that building that is assigned an IP address in that range will display the 911 Caller ID that I have assigned.


Thats it. Don;t read too much into it. It very very VERY simple. (and yes, I would use the analog number if you have one. Just make sure you have the ability to project the Caller ID number out your PRI. If you don;t, you can request this feature from your carrier.

Thanks again for all your help Charles. I will try it tomorrow when I'm back in the office and I'll post more info on it tomorrow.

Does the CESID # need to be in my Shoretel setup at all? Is the CESID # the # that will be used if any of the assigned phones dial 911?

[Plumcrazy09]

Here is what is already setup under IP Phone Map. Looks like each building is already setup but no CESID info is there.

[Plumcrazy09]

After thinking about this (yes I know you told me not to read to much into it), is the CESID # what is sent to 911 and the actual call does not need to use that #?

Example:
Building 2 has an analog line physically at the building (763) 767-5148 and this number shows the location address. I then setup the phone map to use this # so when someone makes a 911 call (which the call would physically go over our T1 circuit) the # sent to 911 would be the 763-767-5148 #, correct or incorrect?

BINGO! You got it!

Well here's some updated info. More config information to start with....

Building 1 = City Hall (main # = 755-5100 analog)
Building 2 = Community Center (main # = 767-5100 DID#)
Building 3 = public Works (main # = 755-8118 analog)
Building 4 = Water Treatement Plant
Building 5 = Fire Dept. (main # = 755-9825 analog)

Buildings 1-4 are considered the HQ site.
Building 5 is Fire Dept. site.

I have the IP Phone mappings as follows:
Building 1 = 192.168.1.0 (CESID = 755-5100)
Building 2 = 192.168.21.0 (CESID = 767-5100)
Building 3 = 192.168.31.0 (CESID = 755-8118)
Building 4 =
Building 5 = 192.168.2.0 (CESID = 755-9825)

Here are the results of what happens:
Buildings 1-3 all are sending 767-5100 to 911 over our PRI.
Building 4 untested.
Building 5 busy signal calling 911 & phone displays "reorder tone".

How in the heck is my PRI sending 767-5100, which is actually my first DID # out of a block of 100, for 911 calls, but if I call my cell phone I see my DID #?

Talk about being confused?

The problem with using CESID is that most carriers will NOT honor whatever number you send when you place a 911 call. They overwrite the caller id field with the BTN for trunks.

[jmccumber]

Our carrier provides the ability to send caller ID based on CESID, however it is a service we have to pay for. At one point they claimed we didn't have the service and our 911 calls sent the incorrect CID. Kind of a mess but as long as they don't mess with our account it works.
