Basic Cisco Emergency Responder question

I'm fairly familiar with CUCM and prinicples of IP Telephony but I'm very green with CER. I have a CER server at HQ that covers a building with 3 floors and about a dozen zones. All of the route patterns to support this have been setup in CUCM and a contiguous block of DID numbers was set aside a long time ago specifically for CER/E911. Everything works fine with E911 at HQ.
Recently a remote office came into play. The remote office has 3 or 4 users. There's only 1 physical IP Phone (for general use). Everybody there will use IP Communicator. All of the VoIP traffic is passing across a VPN tunnel. PSTN calls from this location use a SIP trunk at HQ. I have a couple of questions. First, is it reasonable to route 911 calls across the VPN tunnel to utilize voice gateway resources at HQ? Second, if we do that can a new zone be integrated into CER for this remote office such that calls originating from the remote office will go out to the PSAP via HQ and the PSAP will show address information for the remote office (assuming that all of the paperwork is done with the provider/PSAP)?

Sending 911 calls from centrelized location should only be considered if the SIP provider support e911 functionality and can route the call to local PSAP center where the phone is located. You would need to define different ERL/ELIN for those sites in CER. If that is not an option your only option would be to deploy local POTS lines for 911 calling.

Simple Cisco Emergency Responder Question

I'm setting up CER for the first time. On the CER server in the Convention ERL Data section, when I add a new ERL I am presented with 2 things:
Route/Translation pattern
ELIN
Now, my route point for PSAP callbacks is 913XXXXXXXXXX and let's say for this example that my ELIN is 555-555-1234. Do I put:
R/T Pattern: 9135555551234
ELIN: 5555551234
or am I doing this wrong?

This has nothing to do with callbacks, this is how the emergency call will be routed and what caller ID be presented to provider/911 operator.
For each ERL you can define multiple ELINs, ELINS are the specific DIDs allocated to e911 and are defined in the ALI database that map the address to this number, so each ERL needs unique ELINs, number of ELINs depends on the size of the ERL and how many users are part of it, is if more than one call is made from the same ERL you want to use different one as CER recycles them.
Route Pattern/TP is basically telling CUCM what should it use to route the call out, typically you only need one Route Pattern per location, and by using "calling party modification" the ELIN is used as the caller ID of the call.
913XXXXXXXXX is a CTI Route Point on CUCM that allows callbacks to be redirected to CER.
So here is a high level call flow for outbound emergency call:
1. phone with DN 1000 dials 911
2. CUCM matches Translation pattern in site specific partition and relays the call to 911 CTI RP, or this CTI RP is matched directly
3. The CTI RP is associated with ceruser, and hence registered to with CER
4. CUCM transfer the call to CER
5. CER looks up the details of the caller based on CDP and SNMP locating either the switch port the phone is connected to or subnet (based on config in CER)
6. The switchport or subnet is associated with ERL
7. CER uses the next available ELIN of the ERL, and uses the RP/TP, it routes the call back to CUCM
8. CUCM matches the RP/TP and modifies the calling number of the ELIN
9. Call is send out to PSTN
10. when call arrives to PSAP the ALI database matches the calling number and maps the address of the caller
For the callback, assume the call was dropped and 911 operator dials the ELIN
1. call arrives at CUCM and matches a specific translation pattern that summarizes all of the ELINs
2. The TP prefixes 913 to the called number
3. 913XXXXXXXXX CTI RP is matched, which is registered to cer
4. call is transferred to CER, CER lookup up who was the last caller that dialed 911 using this ELIN (this info is held for up to 3 hours)
5. Call is extnded to the original caller, extension 1000 in this example.

Chris

Phone not showing in Cisco Emergency Responder

We are running Cisco emergency responder 8.5 and have a Cisco WS-C3750-48PS-S Running c3750-ipbasek9-mz.122-55.SE6.bin. Emergency responder is seeing all but one phone plugged into Fa1/0/10. The phone is also not showing up in un-located phones either. That port is configured the same as all other ports. Does anyone have any idea why a particular phone wouldn't populate ER at all? I'm not sure what else to T-shoot. CDP is enabled globally and on that interface.
CDP Information for port:
Device ID: <name removed>

I am pending someone else move that phone to a different switch interface so I'll report back when I get some information on that.

If the problem lies in your computer, im going to guess the problem is the driver for your iPhone.

Cisco Emergency Responder 8.5.1 - Onsite Alert Email

Good Day,
I have a client with CER 8.5.1 and they currently have 2 Onsite Alert contacts configured. The first one in the list is working correctly, and the other day when they had a 911 call placed it correctly sent out an email advising.
The second entry did not get an email.
I have gone through and checked the Cisco ER Group Settings, and have ensured the correct email address is present, but yet my client cliams that emails are not coming through for the one user.
If the SMTP server was incorrectly configured than the first entry would not work, right?
Does anyone know if there is a log that reports if/when emails are sent out, some proof that the system is in fact generating an email and sending it to Exchange?
Many thanks!

You can find logs on the attempted smtp messages by going to CER Serviceability. Go to System logs, CER Server, and then look at the systemout.log files. Do a search for the @domain.com of the full email address. I'm not sure if you will see a failure response, as I don't have any failures to report, but you'll at least see the attempts.
Are the two addresses in different domains? Depending upon how the smpt relay is set up, it may allow messages to be sent internally, but not externally or only externally or not internally - something to discuss with the mail administrator.
Hope this helps.

Basic Cisco 7960 Phone Question

Hi, folks:
I am new to Cisco VoIP solution. I would like to set up a Cisco 7960 phone. When I provisioned the phone, I noticed that there is a parameter called "Admin VLAN ID".
Since my phone is connected to an access port of a switch, I believe it should not use any VLAN tagging.
So I am wondering whether this vlan tagging is only applied when a PC is subtended to the phone? If the PC belongs to a different VLAN, does it automatically change the connection to the switch to VLAN trunking?
If no PC is subtended to the phone, then, does the phone automatically turn off VLAN tagging?
I saw the phone got IP address from the local DHCP server, however, I cannot ping it. So does Cisco phone rejects ICMP packet by default?
Thanks a lot!
Shixiong

The "Cisco" solution to your problem would be to segment your voice and data networks and run QOS on the network to preserve voice quality. A typical Cisco switch port would look like this.
interface GigabitEthernet0/4
switchport trunk encapsulation dot1q
switchport mode trunk
switchport voice vlan 10
srr-queue bandwidth share 10 10 60 20
srr-queue bandwidth shape 10 0 0 0
queue-set 2
mls qos trust device cisco-phone
mls qos trust cos
no mdix auto
auto qos voip cisco-phone
spanning-tree portfast
This config would put a phone in VLAN 10 and either a directly attached PC or a PC hanging off the phone into VLAN 1. You would be responsible for making sure the proper routing and DHCP are available for both your Voice and Data network.
If you are just playing around and want to get a 7960 to work in the data network, remove all trunking info and voice vlan info and the phone should boot up with the same IP scheme as a PC on the data network (make sure this DHCP scope has correct option 150 settings - or this test will be very un-eventful for you - phone will not get a config.)
ICMP is not disabled by default, but if you have a phone that thinks it is in the voice vlan (called admin vlan on phone) but an address on the data network, it isn't going to work.

Monitoring Cisco Emergency Responder

Hi there,
is there a way of monitoring CER for unallocated phones?
Searching for snmp + CER shows up tons of replies because snmp is one of the core items of the CER (used to allocate phones), but I could not find which CER parameters can be monitored with a network management system.
Thanks in advance,
Kai

Hi Jaime,
I checked the release notes of CER. I found following supported switches in 2960 series:
Catalyst 2960
Catalyst 2960-C
Catalyst 2960-S
Catalyst 2960X
Catalyst 2960XR
I don't see 2960-Plus.
Thanks,

Emergency Responder Gateway

I have the following running and testing in a simulated lab test environment
2 - Cisco Unified Communication Manager CUCM 8.6 acting as gateway trunk
1 - Cisco Emergency Responder CER 8.6
2 - Cisco IP Communicators
Everything seems to be working except CER does not seem to be presenting the correct ELIN to the simluated PSAP, it is showing my regular phone number or extension instead. I can see in the CER Call History that it is picking the correct route pattern and ELIN number.
In the administration guide it says that I must configure the gateway to sends th actual calling party number rather than a generic number.
I tried changing various "Calling" settings in my outbound calls in trunk configuration without success. Any ideas?

Not using any calling party normalization css in particular. Everything is default. I simply create none gatekeeper trunk at each CUCM and forward to each other.
In my route pattern, I have Use Calling Party's External Phone Number Mask checked.
What is the correct way to do this in order for the other side to see the modifed calling numbers by CER
Do it at the route group level? route pattern level? gateway/trunk level?
Not exactly sure which settings at which level overwrites the other.
Really appreciate your help!

Emergency Responder (E911) colocation?

I have a client that has a cluster of Call Managers in a european country and would like to use that cluster for an office in Vermont USA and remove a local call manager there. This vermont location currently uses an Emergency Responder server for Enhanced 911 services.
Does any one see any issues using the E911 server across a T1 MPLS circuit.? Does the E911 server need to be colocated with the cluster? Are there bandwidth and latency requirements across the WAN?
Are there any other issues you can foresee having the E911 server there? Will E911 work with SRST in a failure situation?

Many customer use CER for multiple locations within a CUCM cluster. You should be able to do this, as for the configuration with SRST, I am not sure. Since one of the major functions of CER is to identify phones in their physical locations you should be able to configure it such that all emergency calls in the Vermont location would egress their local GW's.
You may wish to address the CER documentation to verify it meets your needs. This documentation can be found at the link below:

Emergency Responder SNMP error

I have a customer with a publisher, two subscribers, and an emergency responder server. Subscriber number 2 had an IP of 10.21.29.100, but it was moved to another subnet recently and the IP was changed to 10.16.29.100. The new IP is configured in the SNMP settings on the CER server. I do not see the old IP in the lmhosts or hosts files and the customer's DNS/WINS servers do not have this IP associated to the server name. However, we keep getting the following email notification: CER Phone Tracking could not get information[using SNMP] from 1 Cisco CallManager(s)
Check EventViewer on CERServer for details. When we check the event viewer it shows the following: failed to retrieve SysOid of a device 10.21.29.100. Does anyone know where the CER server could be getting this IP from?

I think this will resolve your issue:
- Go to the CERAdmin page > Phone Tracking > SNMP Settings and change the Read
Community to " public " for all the switches.
- Then do a " Switch-Port and Phone Update ".
- Next go to all your Switches and configure the following commands
snmp community public ro 1
snmp-server community public ro 1
If you don't want to make your SNMP community public, you can do this:
- On the Call Manager could you go to Start > Programs > Administrative Tools >
Services > SNMP Service.
- Right Click > Properties > Security. In here " add " the SNMP Community String
that you need with "Read Only Community Rights ".
- Once this is done change the SNMP settings on the Switches to match the SNMP settings on
CCM, and CER

Emergency Responder Supporting the US, But Located in the UK

Hi,
I have a customer who has two CUCM clusters, one in the US and one in the UK, who wants to consolidate them into a single UK based cluster. He is aware of the signalling, call set-up latency etc. associated with this design model.
He wants to deploy Emergency Responder to support his US sites.
Based on the design guidelines and network latency ER will have to reside in the UK along with the rest of the UC applications.
Is this a supported configuration?
Does deploying ER in the UK across an MPLS WAN this breach any US regulations?
Many thanks,
Mike.

As far as the regulations I think it depends on the state. For example our cluster is in Texas and I have to provide the floor with our CER. If your MPLS circuit fails you would probably fail over to the local gateway running CME and a pots line for emergency dialing that would be a local number for that campus or site. If it is only a small office I think it is ok but if you have a bunch of floors you would be breaking the regulation here in Texas. I found this online by doing E911 regulation search:
Texas - Texas Statute, Chapter 771.060; BUSINESS PROVIDING RESIDENTIAL TELEPHONE SWITCHES. A business service user that provides residential facilities and owns or leases a private telephone switch used to provide telephone service to facility residents shall provide to those residential end users the same level of 911 service that a service supplier is providing to other residential end users. Tarrant County Emergency Communication District has its own specific regulations for E911; Businesses using a publicly or privately owned telephone switch must be able to provide an accurate physical location and phone number for each 911 call. For businesses, location information must be minimally specified to the floor.
Hope this answers the second part of your question.
Thanks,
Brian Carlson

Modify Emergency Responder E-Mail footer

Is it possible to modify the footer of Emergency Responder Onsite alert notifications at all? Ideally we would like to remove the text at the bottom of the alert email "For more information Click here". We have a varitery of individuals receiving the email and they attempt to login to the CER portal to see more info. We don't have accounts for them.
This is release 8.6.1.10000-11
Thanks!

where you ever able to do this? I was asked the same thing.

CSCur05434 - Emergency Responder evaluation for CVE-2014-6271 and CVE-2014-7169

So, is there going to be a COP file fix released for Emergency Responder or are we expected to know how to download and install the fixed version of Bash from Red Hat as the solution? For Call Manager, Unity and UCCX, there were COP files released...if this is not going to be the solution for ER, it would be nice if the bug report were clearer on the matter.

There is one posted under "CER Upgrade Patch" , at least for 10. The bug report is not clear on that at all.
Turns into: bash-3.2-33.el5_11.4
after installing the patch.

Emergency Responder and Cisco 3850 Switches

I'm running Cisco ER V8.5, and recently installed new Cisco 3850 Switches. All the phones connected to the 3850 switches show a "unlocated" status. I've check the hardware compatibility Matrix for ER V8.5 and the 3850 is not on it.
What are my options for locating these phones in ER and assigning them to an ERL. Manually defining the phones? Is there a patch or update to ER V8.5 that would make a 3850 compatible?

I haven't used the 3850's with ER yet so can't speak to that specifically, but generally speaking you have more flexibility using location by subnets vs switches. Scalability-wise, you can add way more subnets than switches. There's more going on under the hood if you're locating by switches so the process overhead is greater.
The only downside with using subnets is if you need to get more granular with your locations than your deployed subnets allow (ie a single voice subnet for an entire building but you need to define and assign locations at the floor level). As long as you've been a little forward thinking on the route/switch side, you'll be fine.
hope that helps,
will

Emergency Responder/PSAP callback question

Upon an IP phone making a 911 call, does anyone know how long CER "holds" the extension to ELIN mapping for? I remember in older versions there was a configurable time limit that could be extended. I see the calls in the call history, but when I call the ELIN, I'm getting a busy. I'm running 1.2(3) SR1 and can't seem to find this parameter. I'm trying to track down what appears to be a callback problem, however my translations and route points check out...plus this was all working at one point.Should I be able to call these numbers still?

it holds it for 3 hours it can be changed in the Cisco ER Group Settings
