Hi
It is not in Infochannel.
In Infochannel, open the left menu 'Services', and click on 'Service Support Plaza' that appear just below 'Services' and when the central window is updated click on 'Service Support Plaza' Link
this will open a new windows.
In Left menu click on 'Knowledge Base'
In central Window select 'Business Cordless (Refresh)'
Click on 'FW/SW Download Library'
Then 'Administration programs'
And you will find CPM and others FW
Good luck
