Office worker is indeed one-x portal.
When you are in Manager then go to the user and profile setting and press the help button.
This will show a list with what each profile provides.
To be honest, i would use one-x portal and not phonemanager.
If it is only for one person then it is a bit expensive because you need a server.
A phonemanager pro license also enables the office worker profile so take a look in to the licenses section and look for it.
You need to enable phonemanager pro on the phonemanager tab at the user and not use the profile setting.
When you pay peanuts, you get monkeys!
honey, i fried the IP Office !!!
Sarcasm, it's only one of the services I offer.
