Extension Mobility on CME: virtualize your phone :)

I don’t want to discuss the Extension Mobility concepts, google for that, my objective is to note down some straightforward commands for EM on CME. The concept is pretty interesting, you don’t need the ‘button’ command to assign DN on you ephone, rather than DN would be assigned on the ‘logout-profile’. I would change the word ‘logout-profile’ to ‘default-profile’ if I were the Cisco designer, hehe. Because it’s the profile set on the device (phone) by default (when user is not logged in to say more clearly). Oh, another point I need specify here clearly, you will MUST needthe ephone-dn for the number you are going to set on profiles. Some people do not create the ephone-dn for the numbers they have assigned on the profiles and shout ‘my EM is not working! help!!’. Okey, let’s configure EM:

1. Create the ‘logout-profile’ first and assign it on ephones:

Remember to create/check if the DN exists first before going to create the logout-profile, it’s very important if you don’t want to cry later 🙂

ephone-dn  1  octo-line
number 1001 no-reg primary

voice logout-profile 1
user 1001 password 1001
number 1001 type normal
ephone  1
mac-address 001A.6D70.D39C
type 7941
logout-profile 1

Have you noticed no ‘button’ command under ephone 1!!

2. Let’s create the user-profile which would be user specific and users will use it while login:

ephone-dn  6  octo-line
number 1010 no-reg primary

voice user-profile 1
user cisco password cisco
number 1010 type normal

So have you done it? No man, it’s not the time for clapping, what do you think what you are missing? Setting the URL for login through ‘Services’ button right? let’s do it now.

3. Setting up URL Authentication:

url authentication username password

You don’t need to worry about the username/password here, set it as you wish. It’s not the user facing credentials, system will use it. So you are set! Have a test and give a big smile!!

Happy Labbing!!! 😀

  1. Very useful article but what about the command button 1:1, does it have any significance here or will the phone use the extension assigned in the logout profile when the use logs out ?

    I think you can’t!! alphanumeric have both the options for alphabetic+numeric and that’s the best approach to design the feature to accommodate both of them, choose yourself what you need to use but you can’t drop one of them…btw, please don’t forget to put a line here if it’s really there!
