I am installed CER version 2.0.3.1000-7. However they do not have Cisco switches. Is the only option to manually define everyone of the phones? This is a list of everything that I have done do far:
Create 911 Partition on CUCM
Create 911 CSS on CUCM and added Partitions to it (Make sure 911 Partition is first)
Create 911 CTI Route Point
Create CTI Ports For ER
Create Route Patterns for ELINs
Create Translation Patterns for ELINs
Create Translation Patternn for 9.911
Configure Gateway for 911 CSS
Set the CUCM Cluster on CER
Create CER User
Assoicate CER User to CTI Route Point and CTI Ports for 911
Update the ClusterDB Host and change to IP Address instead of hostname
Create SNMP Community String
The steps that I am confused about are:
Create Route Patterns for ELINs
Create Translation Patterns for ELINs
What is needed for these steps, I have read the entire CER Admin Guide multiple times and have tried setting it up however it usually ends badly. We have several departments:
1. Employees (All have DIDs)
2. Students (Do not have DIDs)
Employees can make local and LD calls but students can only make local calls.
Also I have added most of our ERLs. Do I just export the file by XML or CSV and the PSAP will know what to do with it?
Thanks for all the help, this is the first time that we are install CER.

You can still import the phones, just will not show up to any switches. You will have to use CAM then. The phones will show up as unallocated phones, etc. Create the zones based on Subnets and it should.
Instead of using 911 as the emergency number, use a different for TESTING. use something like 920 or something different. Leave 911 to dial Emergency services to the PSTN for now. But use a different number for testing everything. So in the document, use 920 for example where they specify 911 (expect for the RP for 911 which is used for current production).
When you dial 920, it should hit CUCM, CUCM has the CTI 920 to CER. CER knows that 920 is "911" and starts the process of identifying the phone, and which ERL zone it is. Once it figures out hte ERL, it will then want to dial back out to CUCM with the zone exentions, say x4000. Take 4000 for the transpattern to 911, and translate that to your cell number. So basically you are dialing 920 (911) and you are the 911 PSAP center. (your cell phone) Then you can test this out during the day, during production and not interrupt production with current 911 Route Pattern to PSTN.
make sense?

You can manually track the phones using Subnets with the zones.
So if switchA is has phones plugged into with subnet 192.168.4.x, then this would be defined as a ERL.
The IP address is coming from CUCM. It knows if the phones is registered and with what IP address it has been assigned. On your network, you will have to organize your subnets by location. May have to increase your DHCP scopes depending on how many zones you want to define.

I called 3com and they said that the only switches that support CAM are the very high end switches which they do not have.
The other stuff sounds good, I will try that out.
Question:
Do I need route patterns or translation patterns for each extension?
