What is it?

Extension Mobility allows individuals to configure a Cisco IP7960/7940 phone temporarily, by logging into that phone. Oncelogged in, the phone adopts the users assigned line numbers,

speed dials, configured services and other user specificsettings.

Technology:Q: What are IP phone services?

A: Applications that utilize the web client capabilities on IP phones.XML applications that enable the display of interactive content withtext and graphics on Cisco IP phones

History:Evolution of telephone from voice service to new breed of Internetappliance

Business Drivers

Increase and improve personal and workgroup productivity

Increases ROI of IP telephony investment


42/54


Presentation_ID

How Does It Work?

Standards-based architecture (XML over HTTP)

Phone has built-in HTTP client

Phone communicates with back-end web server running application

Anyone with basic understanding of web development and right tools can

create an IP phone service

Web Server1. IP Phone sends HTTPrequest for web page

XML /text

3. Web page sent to IP Phone4. IP Phone parses thefile and interprets howthe page shows on thescreen

2. Server runs a script todynamically builds anXML page to return tothe IP Phone

Login/Logout Behavior / Call Flow


44/54


Presentation_ID

Login Call Flow

1. A user presses the Services button on theCisco IP phone and requests to log in. This actioninvokes a URL for the EM application.

2. The phone sends a formatted XML/HTTP query tothe EM service to determine the state of thephone. The service responds in an XML formatwith "No one logged in.

3. The application prompts the user for UserID andPIN. The user enters the UserID and PIN andpresses the Submit soft key.


45/54


Presentation_ID

Login Call Flow

4. The phone performs a HTTP request and theapplication tries to authenticate the UserID andPIN

5. If the UserID and PIN cannot be authenticated, thephone displays "Authentication Error.

If the UserID and PIN is authenticated, the applicationqueries the Cisco IP Telephony Directory to getthe list of device profiles associated with the user

6. The directory responds with the list of the user'sdevice profile(s). If the list has more than oneentry, the phone displays the device profiles from

which the user can choose


46/54


Presentation_ID

Login Call Flow

7. When the user chooses an entry from this list (or ifthe list has only one entry), the application

generates the XML for the service

8. The application determines the URL of the serviceand posts, via HTTP, the generated XML loginrequest to this URL

Note Extension Mobility looks up the URL in the Directory on the firstinstance only; the URL is then stored as a static variable.


47/54


Presentation_ID

Login Call Flow

9. The service responds in a defined XML format tothe request with a Success (or Failure) message

10. The application returns the correct notification tothe device; the user sees a "Login Successful"message on the phone. The phone restarts with

the user's device profile


48/54


Presentation_ID

Logout Call Flow

1. A user presses the Services button on theCisco IP Phone and requests to log out. Thisaction invokes a URL for the EM application.

2. The application generates the XML to query the EMservice for the current state of the device.

3. The service responds to the application with thecurrent state of device; for example, is

logged in.

4. The application prompts the user to confirm thatthey want to log out.


49/54


Presentation_ID

Logout Call Flow

5. When the user presses the Yes soft key to confirmthat they want to log out, the applicationgenerates XML for the logout operation.

6. The application looks up the service URL andposts, via HTTP, the generated XML to the URL.

7. The service responds to the application requestwith a Success or Failure message in an XML format.


50/54


Presentation_ID

Logout Call Flow

8. The application parses the received XML andcreates an XML response message.

9. The XML gets returned as a suitable notification tothe device, and the phone displays "Logoutsuccessful" to the user.

10. The phone restarts to load the original userprofile.


51/54


Presentation_ID

Login/Logout Behavior

You can establish a time limit so that Cisco CallManagerExtension Mobility automatically logs out users after a certain timethroughout the cluster

It is recommended that you direct your users to log in to their phones

at the beginning of the work day. This practice ensures that their userdevice profile gets loaded on their phone. If they make changes to theirprofile on the Cisco CallManager User Options window, the changeswill apply wherever they log in again. The change will not be applied ifthe user is already logged in.

If the User Locale associated with the login user or profile is not thesame as the locale or device, after a successful login, the phone willperform a restart followed by a reset. This occurs because the phoneconfiguration fill is being rebuilt. Add-on module mismatches betweenprofile and device may have the same behavior.


52/54


Presentation_ID


If you set multiple login not allowed, EM supports only one login at atime on a device. Subsequent logins will fail until the user logs out.

If Auto Logout is not enabled, if users forget to log out of a phone, assystem administrator, you can log them out. Or, another user can log

them out when the second user tries to log in to that phone.

If users are logged out of an IP Phone that has the EM featureconfigured for it, they cannot make calls or check voice-mail messagesfrom that phone until they log in. If they can hear a busy signal afterpressing the Messages button or any key on the touchtone key pad,

then they must log in before using the phone.

Users can log in to a phone that is off the hook; however, their IPPhone will not assume their settings until they go on hook. When theygo on hook after logging in, their phone will display a "Resetting..."message and then their phone settings will be available from that

phone.

User's EM profile does not maintain ringtype, contrast settings, and volume settings;
