Outlook dialer with user and device mode and roaming profiles anyone had experience?

Has anyone had any experience with http://www.voip.com.sg/asterisk/voip_asterisk_outlook_dialer.html

I know Hudlite has an outlook connector but I want to integrate three phone systems over three sites with a single computer integration platform. Currently Isymphony is the only software I've found that is capable of supporting multiple instances of Asterisk but it doesn't have outlook integration.

The users will need to move between desks and keep the same extension number which is why user and device mode will be used and the Windows network has roaming profiles.

I've created a test system of the Trixbox install in user and device mode with Isymphony and the outlook dialer but I don't have the resources to replicate the complete network. The outlook dialer works ok but the configuration requires the device rather than the user otherwise the call request fails. This is what raised the real question, what happens when they move to another desk and the phone on that desk has a different device number (as it would). If the configuration is profile specific then the outlook setting will need to be changed, alternatively if it is machine specific then it should automatically reference the correct phone and all will be ok.

Does anyone have any insight on this or know of another outlook connector that will work (does not have to be free).

Thanks

Kevin
