Extension Mobility Question

Just need to check. When user logs into a phone with extension mobility, will the phone change its MAC address?

Customer has a voice recording application that keys off MAC address and it does not seem to be recording this phone if extension mobility is in use on the phone.

Re: Extension Mobility Question

Same MAC will be use for registration different Device Profile.

From where this App is getting the MAC, via Ethernet header? DeviceName via SCCP Register Message?

Which app is?

I upload a EM file which contain everything that happens when a device logins. (Directory, Sniffer, Tomcat, EM app)

Let us know.

Re: Extension Mobility Question

hi gogasca,

read your attached file called E&M and try to look for the file as your suggested, but no luck.

Test if the Extension Mobility web server is running by pointing your web broswer to


this should display the page:

Cisco Application Engine 2.2

Also no luck to access the sample as your suggested.

Access a sample login at


App ID:emapplication

Device Profile:

Basically we tried to locate the above files in Publisher (CCM ver is 4.1(3)SR1) which has Tomcat Web Service and Extension Mobility activated. What we are interested in is to see whether the end users can login and logout their EM from their web browsers. We've implemented EM from day 1, so users get used to login when they come in to the office in the morning and logout when they leave for the day. Does CCM come with any sample xml program for this? I've known that Cisco IP Phones SDK v4.1(1) comes with a sample Extension Mobility Controller (JSP) for this purpose. Please see the attached file item 21.

Thank you in advance.
