Configuring Extension Mobility in CME

What is Extension Mobility?

Very simply Extension mobility allows users to have temporary access to other physical phones connected to CME and have all of their personal settings such as lines(directory numbers), speed dials and XML services as if they were sitting at their own desk.  Extension mobility is also used in desk "hoteling" environments where during the course of a day multiple people may use a phone.  An example could be a 24x7 call center where 3 users each with and 8 hour shift use the same desk.

Extension Mobility on CME Concepts.

First supported on CME4.2
Every phone using extension mobility has to have a logout profile.
Phones must be enabled to use extension mobility.
A User login profile is configured to allow users to login to phones.
Can optionally support up to 50 Agents using Cisco Unified Call Center Express.
IP Phones must have a screen.
Not supported for SIP phones.

Configuring Extension Mobility User Extensions & Voicemail using CCA

Extensions and Voicemail boxes should be configured prior to enabling an IP phone for extension mobility. The following steps outline how to configure these settings prior configuring extension mobility in the CLI.

1. Connect to UC500 using CCA 1.9.1 or higher

2. Goto Voice > Users tab

3. Configure IP phones with fake MAC-address, for example AAAA.BBBB.CCC1, AAAA.BBBB.CCC2, etc.

4. Enter the ACTUAL extension, Lastname, Firstname, UserID and password. Do NOT configure any more options for the IP phones, such as intercom, paging, etc. Since these configurations will be removed when you enable extension mobility in the next step.

5. Click apply. During this step the user extensions, voicemailboxes and dummy ephones will be created

Configuring a Logout profile on CallManager Express

All the user extensions and voicemail boxes must be configured before attempting these steps.

enable
configure terminal
voice logout-profile tag  (You may have as many logout profiles as phones supported by the hardware)
username username password password (this is creted for this device when logg
number number type type
speed-dial speed-tag number [label label] [blf]
pin pin (optional used for call blocking)
end

Example Logout profile

CMERouter(config)# voice logout-profile 1
CMERouter(config-logout-profile)# user phone1 password 12345
CMERouter(config-logout-profile)# number 4000 type feature-ring
CMERouter(config-logout-profile)# speed-dial 1 6002

Also, remove the dummy ephone(s) created during the initial CCA step. These are the ephones with MAC address AAAA.BBBB.CCCx. You only need the ephone-dn and CUE voicemailbox(s) created by CCA in the first step. Note that IP phones with extension mobility enabled will no longer be managable using CCA.

Enabling a Phone to use Extension Mobility in CallManager Express

Basically, all you need to do is assign the logout profile to the ephone itself .

Using the logout-profile profile-tag where the profile tag is the tag number assigned to the logout profile you previously created

An Example Ephone Configuration
ephone 2
mac-address 0000.D111.B432
type 7970
logout-profile 1

These MAC address entered here is for your "REAL" IP phones. Typically IP phones on UC500 will auto-register with an extension. You should remove this button assignment once IP phone is enabled for extension mobility:

ephone 2

no button 1:x

Configure a User Profile

This is all the configuration that a user will have when they login to a phone using extension mobiltity.  ephone-dn and ephone templates may be used.

Configuration steps follow

enable
configure terminal
voice user-profile profile-tag
name username password password
number number type type
speed-dial speed-tag number[label label] [blf]

CMERouter(config)# voice user-profile 2
CMERouter(config-user-profile)# name user1 password 12345
CMERouter(config-user-profile)# number 5000 type feature-ring
CMERouter(config-user-profile)# speed-dial 1 6002

Note: The extension mobility user ID configured in this step is separate and NOT synchornized with your voicemail userID

Make sure to save both your UC500 IOS and CUE configuration when done.
