Extension mobility redundancy in CUCM 8.5

Hi ,
I have a doubt in cucm 8.5 extension mobility redundancy.
I have 3 call managers in cluster.
1. X.X.X.1 - punlisher
2. X.X.X.2 - sub1
3. X.x.X.3 - sub3
i have configured CUCM X.X.X.2 (sub 1) for extension mobility URL and in exterprise parameter configuration also (service URL). all phones are subscribed this URL and users login.
my schenerio is,
if SUB1 goes down, i change enterprise parameter service URL IP to punblisher. is that enough for users to login to extension mobility?
my doubt is,
in the above schenerio,
users press services button, request will go to enterprise parameter URL> enterprise URL will check for subscribed services> and route the request to the subscribed services for the phones . but here i have subscribed only EM service which has sub1 IP address.
how user can login?
if users can login meas, how that works.
or do i need to create 2 EM service (one for SUB1 IP, another one for PUB IP) and subscribe all the phones with both the services?
so that if subscriber fails user will login another service with has publisher IP?
I have activated EM service in all call managers inthe cluster.
please clarify my doubts.
thanks

Hi
Yes , the extension mobilty HA is avilable starting from V8 .On earlier verions as v 7 is not supported, Please find the below link:-
http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/srnd/8x/cmapps.html#wp1189079
I think you have to deploy SLB (server load balancer) to distribute requests through servers . You can use load balancer as (F5 , or DNS round robin).
Note:The problem , is that the "Login" and "Logout" service URLs can really only point to one IP address. Please find the below solution based on DNS:-
- create multiple DNS records for the same name which will point to two CCM servers running the EM service
- point your EM service URL at that hostname which you have created on 1 step.
- ensure your phones have valid DNS servers assigned to resolve the above
Note: the problem on the DNS is the delay between requests.
Thank you

Extension Mobility Redundancy

Hi,
To cater redundancy for EM we have created 2 EM service: EM-1 & EM-2. I can find both of these EM services on any IP phone, i can login as well. The problem that i am facing is: once i logged in chssing EM-1 or EM-2, if i press the Service button, i can find 4 EM-1 & 4 EM-2 services available on the phone though only 2 (1 for EM-1 & 1 for EM-2) are actually configured. Where from rest of the services are coming?
Has anyone ever experienced such issues?

You may be better served by posting your question in the Mobility forum. This forum is for discussing IDS/IPS issues.

CUCM 8.6.2 - SURL Buttons Issue related to Extension Mobility

Hello Guys,
we are running a CUCM 8.6.2.22900-2 with the extension mobility service. One the user device profiles we have applied several third application services via SURL buttons. Actually I though it does not matter, what device type I choose during the UDP Creation. The Buttons should appear on every model, which support SURL.
When I log into a 8945 with a 9971 user device profile, the SURL buttons do not show. It only works, if I create a dedicate UDP Profile with the 8945 type as base. The same for other models of the 89er/99er Series.
Can you help? Is this a bug?
Thanks.

Chris:
Thanks for the input. We do have the LDAP configured, we are using LDAPS. It is looking like port 636 form the CUP server is trying to reach out to the AD server so we are opening up that port to test if that is out issue. 636 is open from CUCM to AD but not CUP to AD.

Extension Mobility in CUCM 7.1: How to send Userid and Pin with Service Par

Hi at all
is it possible to configure the IP Phone Service (CUCM 7.1)for Extension mobility so that when a user login in EM they dont need to insert the UserID and UserPin???
I think it could work with the Service Parameter but I dont know how.
Have somebody an idea?
Thanks.
kind regards
JosÃ©

Hi!
As far as I know that's not possible and it will defeat the purpose of using Extension Mobility as anyone could login from a phone with no credentials. Porbably you could configure a script or something that allows you to accomplish this, but it won't be supported.

Teresa.

After this the phones are still not registering, I'm suspecting it is the url authentication command, as i can't put the application-name and password after the command, any suggestions would be appreciated. THanks in advance.

Try adding:
voice register global
url authentication http://192.168.1.254/CCMCIP/authenticate.asp secretname psswrd
if still doesn't work try to compare your config with the reference guide here:

Multi forest LDAP and Extension mobility

hello,
We want to support the following configuration:
MultiForest LDAP integration with CUCM 10.5.
So we want to set the "LDAP Attribute for User ID" on UserPrincipalName (UPN). > [email protected]
We also want to support Extension Mobility.
Is there a way to make te login proces easier than logging in with [email protected] and the PIN code?

Unfortunately no, the EM process uses whatever you chose for userID for the login.

Extension mobility - can i have 2 extension mobility profiles with the same extension for a 7970 phone and a 7975 phone?

extension mobility - can i have 2 extension mobility profiles with the same extension for a 7970 phone and a 7975 phone? thanks

Yes, or simply configure 1 UDP and default device profile for the other one.
EDIT: and actually with those models, you should be able to use just one

How to Configure Extension Mobility

Hello friends,
I am presently at crossroad on getting Extension Mobility to work on a CUCM 7(1)2. I have exhausted as many cisco docs on doing this. Please can someone who has not got just the book knowledge but with experience(s) should please give me a detailed step by step way in getting it configured and working!
Thanks!

If you're following this doc:
http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/admin/7_1_2/ccmfeat/fsgd-712-cm/fsem.html
And still can't make it work, you're doing something wrong, that's the doc everyone who has configured EM (and 90% is the same no matter the version) has followed to configure this.
Read the doc, digest the info, then carefully go step by step thru the config.

Strange problem with Extension Mobility and Click to Call

Can anyone explain how is it possible ? Any ideas, guys?
CUCM 7.1.3
PC1 with IP comm. and user1 is logged in to Extension Mobility + Click to Call. User1 can make a call using Click to Call.
PC2 with IP comm. and user2 is logged in to Extension Mobility + Click to Call. User2 can't make a call using Click to Call.
The following error appears on the PC2 screen:
"The call failed. Please ensure you are logged into your Extension Mobility device. If the problem persists contact your phone administrator"

Sounds like a possible permissions issue on the workstation to me. Have you tried configuring one of your test users as the local admin on the workstation?

Failover config for Extension Mobility

Hi,
I have CCM3.3(3) loaded on publisher & subscriber.Extension mobility,Tomcat service is running on both servers.In IP phone services URL, I have givem publishers ip address.In Cisco Extension Mobility Logout,I have configured "True" for Login Service Enabled field in both the servers.
When I shutdown Publisher,EM is not working on all the phones.When I shutdown Subscriber,EM is not working on few phones.But EM is working on all phones when both servers are up.
Should I configure something additional to build redundancy .I want to configure subscriber as primary & Publisher as secondary for EM.
I am using 7940 IP phones.

Text below from Cisco Engineer Marcos Massakawa, about TAC case of this problem with extension mobility.
The problem, as you noted, is that the "Login" and "Logout" service URLs can really only point to
one IP address. In your case, you'd probably have these set up to point to whichever server you
wanted to be the primary one for Extension Mobility. However, if that server failed, the "Login"
and "Logout" services will no longer be useable, since they point to an IP that is no longer
reachable. If you want to enable users to be able to login and logout from the backup server, you'd
have to install EM on the other server, and create a slightly different service name that would show
up on the users' phones as a valid service, such as "Login2"/"Logout2", or "Login Backup"/"Logout
Backup", etc. The service URL for these services would point to the IP of the backup server. It
seems kind of clumsy, but it's a limitation of only being able to put one IP in the service URL.

UCE + Extension Mobility without using CUE

Hi all,
Im trying to set up extension mobility without using a CUE module.
I have the configuration set up correctly, but im having all sorts of issues with the url services.
Can anyone offer any insight / requests for information that might help work this one out?
Cheers

I've thought about this a few times... to me it seems that the options on CUCM just aren't comprehensive enough, and what's needed is an overhaul to the EM service rather than changes on CUCM.
i.e. for 90% of organisations, use sAMAccountName for user ID
for the other 10%, use UPN
But for EM... have more intelligence in the EM service to allow login with extension and PIN, with some intelligence for resolving conflicts if they exist, which then looks up the correct associated account based on the extension number and authenticates with that account name (UPN/sAMAccountName) and PIN against the CUCM DB.

Creating user with extension mobility on prime provisioning 10.5

Hi All,
Does anyone know any document or have any expirenece on creating user with extension mobility on prime provisioning 10.5?
I'm facing challenges on it, appreciate if you have any document or experience to share with me.
Thanks,
Cherry

What sort of issues are you facing?
I'm also having problems, but I think it is system related.
CUCM is LDAP synced.
When PCP tries to provision Extension Mobility Access, it actually seems to be trying to update the user on CUCM (via AXL) (this fails as it is an LDAP user and the values come from LDAP and cannot be updated)
I've got a tac case open.
Bug details are currently hidden - CSCuo11522 - but this one is extension mobility provisioning issue
There was also mention of another bug related to failures to provision users with directory URI's in their LDAP record. I didn't catch a bug ID for this one though.
Cheers,
Tim

Extension Mobility: Automatic logout

Dear Team,
Hi Team,
Our customer requirement is that user should log out at 4:00PM even they are login at any time. Can we achieve this. I know we set the maximum login time but we can not schedule.
Is there any way, by XML application etc. Kindly advise.

The 'extensionmobilitydynamic' table is used to store the information of users logged into extension mobility.
You can do a 'run sql select * from extensionmobilitydynamic' from SSH of a CUCM server to find out the column names and values when a user logs into EM.
Here's a customized query that I came up with (modified from existing CUCM admin sql query), to show a few parameters that I wanted to look at, for EM users :
run sql SELECT device.name AS Devicename, typemodel.name as Model,
enduser.userid AS EndUser, numplan.dNOrPattern as DirectoryNumber,
routepartition.name AS Partition, D2.name AS DeviceProfile FROM
extensionmobilitydynamic LEFT OUTER JOIN device ON
extensionmobilitydynamic.fkdevice = device.pkid LEFT OUTER JOIN typemodel
ON typemodel.enum = device.tkmodel LEFT OUTER JOIN enduser ON
extensionmobilitydynamic.fkenduser = enduser.pkid LEFT OUTER JOIN Device AS
D2 ON D2.pkid = extensionmobilitydynamic.fkdevice_currentloginprofile LEFT
OUTER JOIN DeviceNumPlanMap ON DeviceNumPlanMap.fkdevice =
extensionmobilitydynamic.fkdevice_currentloginprofile LEFT OUTER JOIN
NumPlan ON DeviceNumPlanMap.fkNumPlan = numplan.pkid LEFT OUTER JOIN
RoutePartition ON numplan.fkRoutePartition = routepartition.pkid WHERE
((D2.name IS NOT NULL AND D2.name!='') AND (enduser.userid IS NOT NULL AND
enduser.userid!='')) order by D2.name
Example :
admin:run sql SELECT device.name AS Devicename, typemodel.name as Model,
enduser.userid AS EndUser, numplan.dNOrPattern as DirectoryNumber,
routepartition.name AS Partition, D2.name AS DeviceProfile FROM

I am not aware of a 3rd party software which can do bulk EM logouts at a particular time of the day. However, here's my 2 cents :
- sql query run on the CUCM database to find out the devices logged into EM (probably a script that can run it at a specified time of the day - not sure
how or if it can be implemented)
- from the sql output, send customized http requests to the EM server, to log these phones off EM

Constraining extension mobility

Dear support,
I have five hundred 7942 phones all of the with extension mobility service bound and enabled. The five hundred phones are distributed among 5 different departments. I need to constrain extension mobility within each department to avoid users from one department to login into a phone from another department and make calls. Is there a way to achieve this requirement? My CUCM version is 9.1.
Best Regards,
Roberto.

How are you pulling the billing data? It should show user A's extension so the billing could be associated to the correct department that way. Does each department go out a different circuit or something?
You could put in a feature enhancement request through your account team to possibly have this feature added in a future release if you can make enough of a business case for it. It may still take a long time before it gets added to CUCM though.
